- This little Kriesler is in pretty good condition but it needs work. Why won't it work? What was that noise? I want to see if I can get it in working condition again.

Hi David I remember my aunty having one of these radios. This was in the fifties when I was a kid I remember how she looked after that radio she would put a soft cloth over it when not used she didnt have a TV and it was her pride and joy. I remeber how she would say it was time for the news just how much value she would put into it. Just turning it on was respectful process. Compared to today my kids and grand kids don't have value she showed. To her it was an incredible amazing piece of wonderful equipment. How things have changed. 😊
We worked hard to afford expensive equipment like these radios Bruce. Not like now when you pop down to the shop and buy something that gets sent to landfill in a year or two. We didn't have a lot of money growing up so I can just see Aunty carefully placing a cloth on it to protect it. Thanks Bruce 🙂
These radios are windows into the past, that’s what makes your work so interesting. Thanks for another interesting video.
Hi birdie399 , agreed! thanks 👍🙂
You are the Sherlock Holmes of radio restoration/repair, always interesting to watch.
That would make my wife Dr Watson, Thanks Pozer714 😉😀
Thanks for the great restoration video. You are informative and quite easy to understand when speaking about these radios restorations. Thanks for sharing.
Thank you LUCKYLARRY, I appreciate it 😃
I don't know anything about about radios but I find your videos absorbing. Many thanks
Hi tegwyn7, thank you, I hear that a lot, cheers 👍😃
David, I have been watching your videos for about 2 months now. I appreciate that you are learning electronics but I believe you have a gift for it. I am retired and I have extensive but stale experience in electronics too. I really appreciate the high technical content and theory that you present when repairing these items. Also, I am amazed at the beautiful finished product. Keep up the great work.
I have been repairing several radios, all tube models and I am inspired to continue with them even when components fail and I have to use theory and measurement to figure out what went wrong. Your work is inspiring. Thank you for you presentations and keep at it!

Hi John, thank you, you are very kind. It is gratifying to think that I can inspire anybody, I hope you enjoy your projects and you get as much out of it as I do. Cheers 👍🙂
The capacitor has become "incapacitated". That is funny. I have never heard anyone say that obvious thing before! Great.
ha-ha... it is pretty funny, don't know why I thought if it, Cheers Nathan 😄
Thanks for bringing me your work, I very enjoy watching you restore these old radios.
31:10 the female voice is saying: " xxx doing business. xxxx.. is very simple " it is a Cantonese program.
Merry Christmas sir~~
Hi Lan Li, thanks for that, so I was listening to Hong Kong. Thank you and Merry Christmas to you 😃
David Tipton in Australia SBS radio and TV always provide some foreigner language program, which included Japanese, Mandarin and Cantonese. : )
Very Very nice work sir! It looks and sounds fantastic! I love your technique and gentle voice, and general way you go about these. Such a great video. What a beautiful radio.
Hi Gregg's Vintage Workshop , thank you. I see you have some videos too, I'll check them out 😃
Thank you sir, be sure to subscribe. I have some pretty cool projects slated in 2020.
A neat looking looking little radio and a job well done on the repairs to make it operational again. Best, Don
Hi RestoreOldRadios, I have it sitting on a console radio and it looks good with its rounded shape, Cheers and thanks
Hello David,
All the best to you and your family for the festive season.
Your multi camera shots and overall video production are a real credit to you.
Congratulations and please keep up the good work.
You have created a wonderful channel.
Cheers from a smokey, burnt very sad Sydney, New South Wales.
Thank you for your kind comments Gregory. All the best for Christmas and the New Year. This is the worst fire season I can remember and no sign of rain. Stay safe 👍
It is encouraging to see you do this and even though handicapped by having only minimal information/specifications, you have still come up with a nice sounding old tube type radio. I now know in Australia it is a Valve type i suppose, but all the same, any radio that old that works that well and looks that neat is well worth owning. Good job once again David Tipton.
Hi Jeff, thank you for your comment. Getting information can be a challenge, some smaller manufactures didn't publish any information at all but you can usually work it out 🙂
Hi David. You do nice work. Having just built a 1 RF / 1 IF home brew superhet, (6BAC, 6BE6, 6BA6, 6AT6, 6V6, 6X4) I have been thinking about the issue of isolating the tuning condenser. I think the isolation is two fold: One to allow the ground currents to be directed using wires rather than interacting with other ground currents in the chassis and two, possibly more important, the condenser is a microphone in that vibration will modulate the tuning. So vibration from the speaker can cause tuning modulation at audio frequencies, resulting in a rough sound methinks. I have mine hard mounted and am experiencing some issues that I think may stem from the above considerations.
Hi 984francis, that's what I was thinking. It's to stop the tuning plates resonating and/or provide a single path to ground. I'll have do a bit more digging. I suspect if I ask 10 people I would get at least five different answers 🙂
Hi David just an update on the Collier & Beale set I'm restoring.. I already powered the radio up with a dim bulb tester and at first it didn't give any sound at all ...and guess what, the output transformer was open. So this video is actually perfect timing! I just experienced what you experiened in this video but it took me ages to figure out what the problem was until now. Luckily, I bought another set that had a speaker with a good output transformer and used that to test my recapped radio. Now it works fine and produces great sound. Thanks for sharing this. Btw, congrats on the steady increase of subs. You deserve it! Merry Chritmas and a Happy New Year!
Hi Bj, that's great to hear, that WAS good timing 😃 I usually connect a meter to the plate to test the output transformer when I power the radios on but totally forgot this time. It gave me a chance to explain though. good work, I'm very happy 😃 All the best for Christmas and the new year Bj 👍🙂
Thank you David, I just picked up three 11-20 in the last 2 weeks, I looked on RUclips for repair videos for the Kriesler 11-20 but it looks like you are the first, Now looking forward to working on mine, just waiting on some parts.
Hi Melissa, Three! I bet they are all slightly different. I hope you can work out the mod status better that I can. If you have one with a 6V6GT output valve can you let me know the bias voltage please. I have mine going at the moment as I work and it sound pretty good for a small radio. P.S. I should have sent you the link to the video 🤦♂️😃
Yes I had a quick look at the other 2 radios and they are all different, I did see that one of the Radios has 2 valve that don't have the black base, they are more look like a modern valve, the one I am working on first looks to be the 11-20A and has had no components changed only the dial cord but the housing is very badly damaged, unfortunately ill have to repair it and paint it.
It's always fun watching your videos.
Hi Phil, thank you, so glad you enjoy them 🙂
Your an amazing Technician David and it sure has been my pleasure viewing all your work this year. Hope you and yours have a wonderful Christmas and a Happy New Year mate.
Thank you Gilbert, it has been my pleasure. All the best for Xmas and a safe and happy New Year 😃
That’s sure a beautifull radio, I really enjoyed watching restorations, thank you so much for sharing, I wish you and your family all the best and have a happy new year.
Thank you Tommy. All the best for the new year 🎉
Very good David! I've enjoyed the restoration. The only thing I've noticed is that you didn't mention if you care about the new Capacitor's outer foil connection... Old (Wax) cap's had a black line at one end and even stated "ground" or "outer foil", new cap's don't (maybe nowadays this is no longer needed as the components are placed on printed circuit boards) But in old radios, the outer foil can be an excellent hum antenna if connected backwards....
Whit the help of an oscilloscope and your own hand, you can easily find the outer foil in new capacitors so you can mark it in order to respect the original connection.
Thank you for sharing!!! Happy new year!!!
Hi Jorge, thank you. I don't worry about the foil end although it is in the back of my mind if a noise problem arises . Speaking to an old radio tech he laughed off the whole idea. If there is a problem, moving components with a chopstick can help locate it 🙂
Funny answer. Most of all, very.... "professional" 🤦♂️
@@jorgeargerich1091 ha-ha... sorry Jorge, what I should have said is if there is an interference problem use a non-metallic probe to move suspect parts slightly to see if it changes the feedback sound to isolate the source 😄
Well done! Enjoy your videos tremendously. Happy holidays from Virginia USA.
Hi Virginia 👋 we spent time there on a driving holiday and loved it. I came home and listened to Creedence Clearwater Revival songs for ages. I know they were from San Fran but their music reminded me of the South 😃 All the best for the New Year 👍
32:30 The broadcast range starts about 5 Khz short of the bottom end of the band(535 Khz for the band, 540 Khz) for this radio, but at the other end(top of the band) goes 35 Khz into the Narrowcast range above 1605 Khz(this set tunes up to 1650 Khz).
Thanks Neil.
@neilforbes416 these days its in the 531-1602 Khz range.
A great video David. I’m making this comment 4 years late but I think it’s worthy.
The el33 and 6v6 are not really equivalent. The el33 needs about 3 volts bias and has twice the gain of the 6v6 which as you pointed out needs much higher bias. Who knows whether in the day they changed the bias resistors for the different valve's. ,!! According to radiomuseum Philips made el33 valves in Sydney up to 1944.
I have an air zone 414 which is of the same vintage as this plum pudding and similar circuit. It arrived with a 6v6 output valve but luckily in my junk box I found a good el33. I was watching exeters lab where he was restoring an air zone like mine and found that the 6v6 can damage the radio. So that may be the cause of the oc output transformer in the plum pudding. And the 6v6 could be weak giving confusing results.
Anyway I enjoyed this video, thank you David.
I don't recall the details of this one Robert. It was early on and I had even less clue as to how these radios work than I do now. You would think the bias resistor would need adjusting to suit either valve. I would also wonder it the OPT specs would need to be different and the power transformer upgraded to handle the extra filament current draw of the EL33.
Dave - in my opinion you are one of the best vintage radio repair/restorers on YT right now. Very enjoyable to watch and learn "how to do it" in your videos.
I wish you and your family a super Merry Xmas and a safe Happy New Year. :-)
Thank you RoughJustice 2k18, I am happy that you and others get something from what I'm doing, it's very encouraging, thank you. Please accept my best wishes for a great Christmas and a very happy New Year 😃
Great restoration David, the set cleaned up nicely too. The negative bias voltage derived via a power transformer winding for the output valve is quite a common arrangement, most of the NZ valve sets I've repaired are the same, it fooled me initially until I figured it out. I liked the way that capacitor failed with a 'crack', normally for me they short or getting stinking hot! Happy New Year and look forward to more video's in the future 👍☺
Hi glenz1975, I guess you are referring to the centre tap of the power transformer and that's common on Aussie sets too. I knew something was wrong when I heard the cap go and was waiting for smoke. The increased hum gave the culprate away pretty quick. All the best for 2020 👍😃
A suggestion, instead of mangling those threads with pliers. Try threading on another nut. Then you can turn the nuts against each other to turn the screw body. Tighten the top nut against the lower nut to adjust clockwise and turn the bottom nut out into the top nut for anti-clockwise. Hope that makes sense. :) Really enjoying the content!
Hi Richard, I am aware of that method and have used it regularly particularly for removing studs but to my shame didn't think of it in this instance. After the video it worried me so much I removed the base cover and ran a small die along the thread and cut a new slot in the screw with a Dremel for the next guy. Thanks for the kick in the pants Richard 👍😃
@@DavidTipton101 Haha. No kicking intended. Like I said, I'm really enjoying watching your workmanship! :)
Hi David, Nice work and video! I have just finished one of these sets myself and it was interesting and amusing watching you find some of the same issues I found, including the output transformer. I managed to salvage mine - the open on the secondary was on the very inner winding and I managed to hook an and out and reconnect. Cheers!
Hi Bob, you were lucky to fish out that wire, mine have always been in the primary and the bottom layer. They are a nice radio Bob, mine works well. Thanks 👍😀
@@DavidTipton101 Ah yes - I should have said the secondary on mine. Cheers
Hi Bob, you did 🙂
@@DavidTipton101 I must be going senile - I meant the primary. 🤪
@@bob_mllr Haha...🙂
Hello, my name is Cleber, I am from Brazil, I follow your work, congratulations !!
Hi Cleber Ferreira de Almeida, thank you 🙂 Hi to Brazil 👋
Great video! Love the different camera angles and picture in picture.
Hi ljetronic, thank you. It's a long process but I'm happy people appreciate it, thank you 👍🙂
Great video as usual. Although you indicated that there was a difference between yourself, fellow Australians and New Zealanders, I really couldn't discern a difference. Though those that live in the northern US states say they have a hard time understanding we southerners, I have a hard time understanding those from the New England states. Oh well. Hope it isn't too hot for you there. Merry Christmas to you and family!
Hi Phillip, Some new Zealanders have close to an Aussie accent and it's hard to tell sometimes but a strong Kiwi accent will sound "I" as a "U" so fish and chips sounds like Fush and Chups and six is sux. They also elongate the "e" so the e in ref would sound like reef, so refinish would sound like reefunush. We aussies are just slack with pronunciation 😌 Thanks for your comment and Merry Christmas to you and your family and all the best for the new year 🎄😃
I have a couple of those plum pudding radios I picked up cheap at the HWS auction in Brisbane. Haven’t looked at them yet. Your video gives me the confidence to tackle them! Only problem which I don’t think you encountered was both mine have cracked or missing Bakelite strips on the speaker opening. I’m not sure how to handle something like this. I’m sure there are restorers who can make substitutes pieces and glues them in so as you’d never know, it I think it’s beyond my skills. I bought the second radio for spares to fix the first, but looking at them they are so beautiful I can bring myself to rat one of them to fix the other…
Hi ctho admin, both should be a easy fix, 'usually' just replace the caps and it will work. If it were me I would take a mould of some of the good fins and reproduce them with epoxy putty or JB Weld or even two part moulding plastic, whatever suits, trim to fit and spray them with mission brown and black simultaneously to create a Bakelite look or once again whatever suits you, you might be able to use a paintbrush in a similar fashion 😀
@@DavidTipton101 you make it sound so easy David! I’ve seen your work, it’s radio restoration raised to high art! I particularly loved that Christmas radio you built. Hope to meet you some time at the Brisbane auctions. Haven’t gone in a while. I will try what you said for the plum puddings once I have handled the electronics side.
@@cthoadmin7458 Good luck with your radio. Fixing the case won't be easy but just experiment, that's all I do. Please say hi if you see me on the club day 😀
@46:13 David I have to point out that even though the peak is correct you could have the situation where some of the IF coils have drifted up from the 455kc and some have drifted down. This would give the peak correctly but you cannot know if that peak could be higher unless you trimmed each coil. This could also affect the selectivity particularly on SW.
Hi jonka1, yes that's a good point, I hadn't thought of that, thanks 👍🙂
Thanks for your videos David. You've certainly entertained and informed me, and a lot of people, with your careful and expert work. Have a great Christmas and see you in the new year! Cheers
Hi Tom, thank you so much, I'm glad you get something from my hobby videos and hope it continues in the new year. All the best for Xmas and the New Year 👍😃
Thanks David for another fine video. I always find your videos entertaining and educational. Looking forward to more. Have a wonderful holiday and see you again next year.
Hi Phillip, thank you. I have a few in the pipeline and a timber mantle one I am anxious to do. All the best 😃
Good to see another video, 👍it came out great. Happy New Year to you and yours.

Thanks Jerker, please put in a good word for me, it's been slim pickings the last 50 odd years, Merry Christmas 🎄😄
Another enjoyable and informative video David. If it's a plum pudding needs a 6d piece (6 pence coin) putting in it 😆😆

Hi Quantum Leap, thank you. Merry Christmas to you and all the best for the new year 😃
As always David , a masterful piece of restoration.. The Kriesler is the same age as I am.. Perhaps if I pop over to you in Oz, you can do a restoration & make-over on me to give us a new lease of life ? My better half say's I need at least an alignment job so I can receive her instructions clearly.. Personally, I think I'd prefer to stay slightly 'off' frequency !
Ha-ha, hi Pete. If I could restore people I would be first in line 😄
as always a delight to watch your work David! Merry Christmas !!!

Those Kriesler purple bakelite cases really look good. I think I'd really like to find this SW one under my Christmas tree.
Hi Wayne, they look pretty brown in the flesh. It would make a great gift 🤔🙂
Thank you David, another great project to follow, can you slow it down a bit! Usually you have a nice and slow / easy flow to your commentary which is part of the charm of listening to you, might be me, but sensed a different style of delivery in this video "rushed" . Hope you don't mind the feed back, hope you and yours have a lovely Christmas and a great new year and once again, thank you for all your great videos. Graham from the UK.
Hi Graham, I noticed that too and went back and tried adding pauses in the video but it's not easy. I'll fix that in later videos. I might have been feeling rushed as we approach Christmas, I had a lot to do. Always happy to get feedback, the videos are for you after all. Thanks for the comment and I also wish you all the best for Christmas and the New Year 😃
Nice work as always! Did a nice job! I enjoyed this video!

Great job David. Shame about the broken adjusting screw, and the open circuit output transformer, but you can’t win them all! Case polished up a treat to complement all the hard work you did inside.
Spreadsheets for transformer specifications? I vowed I would never even look at another spreadsheet when I retired lol.

One of many nice tube type radios. Those are from the good old days. I don’t see a year, but I’m going to guess this one’s a 1946. A time in which American workers took their time and pride into these wonderful, high-quality works of art. Try to put this radio and a modern Chinese radio side by side, we both know which one ☝️ will sound better. From the steel chassis to the tuning gangs, high-quality speaker and metal knob shafts, to the dial cord to the dial light, and the glass face, this radio is like a ‘57 Chevy. All this under a very handsome Bakelite case. Painted on numbers, yes, when everything was better. This radio is worth teasing your kids or wife with. Just set it on the table and call everybody to Christmas 🎄 or Thanksgiving dinner. Yes, a little plum pudding. All the nice radios of days gone by. Bakelite or wood, they’re really the radios 📻 that should be in houses 🏡 across America. I think 🤔 they should be a living room radio. Not for the garage, bedroom, basement or shed. A basement may be fine if there’s some kind of value that I know, but don’t know how to communicate it. Simper way to say, if the basement is converted into your living room. Some unconventional houses are done in ways some people don’t think are possible. I like that little Spanish jingle, which starts at 12:47, and lasts until 12:53 on the video timing. Can you tell me who it is, or the name of the song? I’m guessing Selena. Please keep these great radio videos coming. If you come across any cardboard cased radios 📻, please don’t turn them away as some RUclipsrs do. They are probably 1940’s and 1950’s radios, which are much sturdier than Crosley record player radio stereos today, produced from 2009 to present 🎁. These 1940’s and 1950’s cardboard cased radios are still a major piece of history. These could be 1960’s. I’m a poor guesser at when cardboard cased radios, record players, and record player radio combinations came out. Great 👍 videos. Keep ‘em rollin’.
It's very nice looking radio Jeffery. It was made in 1948-50 and was the model after the Beehive I think, it was made in Australia. The spanish jingle was the Swedish group ABBA, the song was Chiquitita ruclips.net/video/p4QqMKe3rwY/видео.html
I doubt there are any cardboard radios made in Australia but I have seen them on American RUclips channels, I certainly wouldn't turn them away, they would be far too interesting. All my radios go on display in my home 😀
Verry nice plum pudding ;-) . thank you for the video .
merry christmas to you

I just discovered from the Hallicrafters Groups site, if you are cleaning plastic covers (side with no lettering) try dilute toothpaste with a cosmetic wipe. Not fancy toothpaste, ordinary toothpaste. Did a great job on my s meter.
Hi Hallicrafters Rehabs. Are you referring to the dial glass? it was actual glass in this radio. Toothpaste will work on plastic, it contains an abrasive, good tip, thanks 😀
Sorry missed the reference to glass. No worries.
Thanks and best wishes from Scotland

Hi David from UK, thank you for another great restore. As a newby to the hobby could I ask you to show where you hook up the signal generator for the different stages of alignment also can I say how helpful it is when you show the schematic in relation to the part you are working on. Looking forward to the next restore merry Christmas to you and yours.

Hi Ross, thank you and Happy Christmas and all the best for 2020 to you 😃
The rubber grommets under the tuning cap are for RF isolation, you can't have any connection between the tuning cap and the chassis.
Hi Wayne, not sure what you mean there, plenty of radios had the tuning cap hard mounted to the chassis and of course the caps are generally electrically grounded to the chassis by a braided wire. Do you mean in a vibration sense? 🤔🙂
@@DavidTipton101 It is still a lot of VOODOO to me, I am just starting into this field. Mr Carlsons lab has a LOT of videos, on at least one, he explains about the isolation needed on the tuning cap. Yes even though it is grounded in another place, RF does not act like AC or DC voltage, like I said, VOODOO to me so far. I will continue to look to find where he explains why, there are a LOT of videos to sift through.
@@wayneparris3439If you can locate Paul's video I would be very interested. There was a post I read some time ago that postulated it was to isolate the tuning cap from vibration from the speaker through the chassis to the TC which could cause the TC plates to vibrate and affect its resonant frequency.
@@DavidTipton101 I have been looking and I asked for help on the Pateron forum also. LOTS of hours of video to sift through! He made the comment almost in passing while explaining about the tuning cap and why it was connected the way it is. I tried a search in specific about RF tuning cap and no luck. Still looking!! :D
@@wayneparris3439 Don't be too concerned Wayne. i just did a Google and there is so much conflicting info I don't know what to believe.
good to see u put a mains fuse in, definitely could save the trani . you can peak the short wave bands in the same way as MF. ps 6x5 rect tubes with flat plates are known to short :)
Hi willrobbinson. I usually put a fuse in particularly with the 6X5 in there. Yes, you are right about the SW band, thanks 👍🙂
Fascinating, I've never seen a Receiver with abbreviated State names for bands. I finally figured that out. U S. broadcasters, hammers. radio types transmit licensed call signs not abbreviated, state letters.
Hi Craig, yep, two letter call sign with the state number in front 👍🙂
Nice job on that radio. Looks great. Glad you got it working good. Have a very merry christmas and a happy new year. Take care, Great video. 😆

Radio New Zealand International are still broadcasting, unlike Radio Australia. I still listen to them on my FRG-7. They started broadcasting DRM digital regularly a few years ago.
Hi Wenlocktvdx, Thank you for that info, I can pick them up easily from my location. Yeah, unfortunately 'we' decided to kill off Radio Australia shortwave and we can stream it now. That's technology 😌
Happy New Year David!
Hi Martin, thank you. all the best for 2020 🎉😃
Hi Dave , Why didn’t you rewind the speaker transformer instead of looking for another ? Again it’s wonderful video , thanks for sharing and we wish you merry Christmas and prosperous and happy new year 🙏
I tried to dig out the windings to see if I could find the break. The secondary windings are on top of the open circuit primary so I would have to remove them first. If I could get a winding machine I would be happy to try that, sounds like fun 😃 Happy Xmas to you and your family and all the best in the new year 😊
Thanks my friend .
Very nice ! I can listen to Radio New Zealand late at night here in the USA :)
Wow, that's interesting, I live 'next door' and didn't know about it till then. We have a close relationship with NZ but they keep beating us at footy (rugby) 😄
Love your videos. RNZ could have been 9700kHz to the Solomons/PNG or 9765kHz to the Pacific. I can get their broadcast targeted to the Pacific in Southern California in the afternoons, but it's weak. The Asian station could have been China Radio International on 19m band; CRI took over some of the shortwave frequencies Radio Australia used when they shut down their SW transmitters.
Hi Mike, thanks for that info. One comment said it was Cantonese and translated it. It's amazing to get signals in California from NZ I'll have to do a bit more SW surfing 👍😃
35:06 David: I don't know how radio's work, I'm just making this up as I go along...
35:13 Me: /sighs
Hi Matthew, It's kinda true, I'm learning this on the fly but problems like this make me nut out how it works 👍😃
Amazing work ...have great happy new year
Hi 208raven, thank you. Seasons greetings to you 😃
That was Vietnamese. My wife is from Saigon,. nice job again.
I can imagine Wisnston puffing away at his cigar listening to that.
Hi Paul, thank you. Another person commented that it was Cantonese, are they similar I wonder 🤔🙂
@@DavidTipton101 not really :)
was wrong. she said it was Chinese. must be more similar than I thought.
@@myfarawaytales ha-ha... thanks Paul 😄👍
An odd looking radio, but working well after you set it up. Is it a hard early plastic case? Strange colour they chose for the case, but then I was not around to see what the trend was back then.
Hi bob4jjjj. It's made from Bakelite, a very early moldable plastic. It is difficult to colour Bakelite so most were a similar colour to my one 🙂
@@DavidTipton101 Yeah I thought it was made of that stuff, very easily broken early plastic. The other color appeared to be an Ivory color. Still a neat radio though and it looks compact for its time. Do you not change the electrolytic capacitors as standard? Yes, I know you said it was just going to sit on a shelf. Thanks for the reply.
@@BoB4jjjjs Normally I would because the original would have been paper and well past their use by date. I didn't on this one because there was no hum and they had been replaced previously. As I found out, being newer does not make them reliable 😄
@@DavidTipton101 No, your right, I think some of the newer ones are more prone to fail.
Thanks for the reply, Merry Christmas and a Happy New Year when it comes. All the best in 2020.
Thanks bob4jjjj and all the best for 2020 👍😃
The analog meter you were using to measure the bias may have been loading the circuit, giving you the lower reading. The digital meter is probably a 10 or 11 meg per volt where the analog is probably 20 to 50k per volt. Nice work! 👍👍
Hi Robert, you are right, I ditched the analog for the DMM. I was trying to do the right thing but realised it was not right at all. I'm always happy to lean and appreciate your feedback, Cheers 😃
I like the analog for alignment because the needle swing is easier to peak than following a digital reading. And on some pre-1950 radios you have to check the schematic to see what meter was used to measure the voltages. Especially on pre-war radios a digital meter will read too high because you are not loading a circuit.
David Tipton Good morning, David, from N. W. Ohio (Toledo area),
This is the first video of yours that I’ve seen, and, I quite enjoyed it.
I managed to acquire an F.E.T. VOM recently. It has the advantage of high input Z, while displaying on an analog meter. It also is portable, running on batteries, and does not have a special probe, with a difficult to obtain vacuum tube for AC measurement. It also is completely isolated from AC mains, and so avoids the problems associated with ground-loops. The primary battery is a nine volt “transistor radio” battery. Current draw is 200 mA, so it’s a little hard on batteries. It does not have the temperature stability problems associated with VTVMs, so you can just turn it on and off as needed. I’ve added an LED and a couple of steering diodes so that I get reminded to turn it off when not in use... I think I may use a wall-wart. And an LM317 to produce a regulated 9 volts when using it on the bench. That would eliminate the battery drain issue, and since I rarely use that anywhere but on the bench it wouldn’t be a problem. I’ll just leave the battery connection in, should I need to take it anywhere. They appear every once in a while on eBay, and I highly recommend one as an addition to your bench, if you can find one.
@@harryshector Thanks Gar, I haven't seen one around as yet but will keep my eyes open. The only one I've ever seen was a Micronta brand and that was a long time ago. Thanks for your comment, hopefully I'll get lucky one day 🙂
It happens that the one I got is a Micronta. It is a 'bench grade' instrument - not accurate enough for lab work, but is fine for aligning radios and such. I hope you can find one. They aren't common, but, interestingly enough, the JET used in it is still available. I bought a couple of them, just as insurance. The manual that came with it was a reprint of the original, and did not have a schematic n it (it was the last page of the manual.) But, I found I found a fairly legible copy of just the schematic on an antique electronics site in Europe, so I now have the complete manual. Actually, I found it on a couple of different sites, and using both schematics, was able to suss out the illegible parts.
Another fascinating restoration David, your transformer load calculator spreadsheet looks very useful, is it available for download anywhere? Happy Christmas.
Hi Steve, I have sent it to you. If others want it send an email to vintageradioaus@gmail.com
GREAT radio dave
Thanks Andy 😀
Nice working
Hi Rssuthar, thank you 👍🙂
Don't fully understand the theory and practice associated with your dim light bulb. Have you done a video about it?
Funny you should ask Jeremy... ruclips.net/video/ykUlzhCTLvg/видео.html 👍🙂
Hi David. Quick question. At time 20:51 in this video you mentioned a solder product called Quibbs or Quidds, a pre-tinned wire. Would you give us the exact name so we call look them up on the internet for a purchase. Thank you.
Hi Martin, the trade name for them is Quigs and later Kwikettes or you could just call them pigtails. They were made by Sprague in the US, I don't think they are made anymore. I make my own as I did in the video or, If it's a component I'm replacing I wind the pigtail using the lead on the component, it shortens it considerably so it's not always practicable in which case I will use a ready rolled Quig 🙂
Re the dial pointer, keep in mind that station separation was changed from 10Khz to 9Khz in 1978 so the pre-1978 dials are now out of whack to that extent.
Hi James, thank you, you are spot on. I use 4KQ as my main marker as the other stations are off a bit. I think 4KQ was 690 pre 1978 and went to 693 after so not much out. I will keep that in mind in future as I sometimes wonder why stations are out. Thanks for the reminder 👍🙂
Interesting scale, covers the whole world
Hi Latürnich, I noticed that too 🙂
How about a link to your spreadsheet? Good job though!
Hi pi-duino. If you send an email to vintageradioaus@gmail I will send you a link to the file 👍
Consider rewinding the primary. I started rewinding transformers at 15 yrs old and once you do one the fear goes away. Also your radio is more genuine.
I did try and unwind it jonka1 but I couldn't separate the secondary without damaging it and I don't have any wire to rewind it. I was hoping the break was near the primary terminals. I don't fear rewinding I just don't have the materials 🙂 I'll see if I can gear up for it 👍
@@DavidTipton101
Thanks for your reply David. I wish you well. The other option would be to alter the secondary turns on one of the others that you tested.
Please can you give me the selution to avoid the nois in AM radio by the effect lighting fiting or the electric generator sorry for my English thank you
Hi Eng Elc, There may be ways of adding filters but I can't answer that. I can only suggest moving the radio or the aerial or if it doesn't have an aerial connect one. I hope that helps 🙂
lovely restore, need to get a valve radio :)
Everyone should have at least one valve radio 🙂
@@DavidTipton101 you know what to do then :) we are 240v as well uncle David :)
@@lookoutleo 😄👍
Perfekt !. What to do?, Can be replaced with extremely difficult to get (in Poland) EBC41 tubes. (Google translator;-(
Hello Wojciech Domagała 👋 I think the ECB41 has a different base. The valve worked OK so I left it 🙂
Witam Wojciech Domagała 👋 Myślę, że EBC41 ma inną bazę. Zawór działał OK, więc go zostawiłem 🙂
I like this work
Thanks you Rajesh 👍🙂
35:08 If you turn the schematic representation of valve 6X5GT, you get a "sad face"!
🙄
can i ask where can i get some of those grommets you are using for the tuning forks...?
Hi Mike, the grommets are in an assortment case from eBay 👍🙂
@@DavidTipton101 good thanks....so to search for them, do i jst type in rubber grommets?
In eBay yes, search "rubber grommets" There is a wide selection available so make sure you get what suits you best. This is the one I got, on the australian eBay site of course. You might have to copy and paste it in your browser address line:

you should check mr carlsons lab, he makes a lot of tube equipment videos, and he has a cap leakage tester he have shared, and you can build it yourself, a lot of good info there
Hi Alf, I am aware of Mr Carlson and watch most of his videos. Thanks 👍🙂
You should watch the Mr Electricity guy on youtube. I seen him rewind a transformer like this, quite interesting. Good vid BTW.
Hi Thorn Mountain, thanks for the tip, I'll check him out 😃
muchos modelos parecian tostadora de pan. 👍
Ja, ja ... Parece una tostadora M.B 😄
