Great work Shango66! Back in 1979-1981 I bought a Sharp boom box and I messed around with the tuning coils and it was really messed up. I was around 16-18 back then. (My dad was a TV radio repair guy and He could have fixed it but I did not want to embarrass my self.) So I took it to a official repair shop in Lancaster, PA around 1982-1984 thinking they would be able to re-align it. Nope they wanted to just replace the entire main board, but it was no longer available. So I took it home and aligned it as best as I could with no signal generator just radio stations in the area. Move up to 2009 I had a surround Blu-ray system with two if the audio channels out. Took it to a shop in York PA. They had it about a week only to tell me they could not get the main circuit board. I found it shocking that these electronic repair shops are just weak in their repair skills. Now this one I figured it was one of the tiny output IC but it was micro so I did not dare to fix this on my own. I eventually bought the IC and sent the board away to a shop in New York, it came back but now the unit will not even work since it now shows a short in it. My error since I did not send the whole unit so they could test it. I eventually got a similar unit that had a disc problem and swapped around boards to have a working unit. So much for the Good Will deal/rescue.... Sometimes I am like a animal rescue person with these things.
Heh, im currently fixing an Aiwa NSX-D5, slowly fixing it for a customer, im sure 80% of repair shops woudnt even know how to revive the VFD displays or properly adjust or fix the tape decks, or even fix the cd player, Sadly the BBE sound thingie is not good, the IC left channel is half dead and no way to get another IC, but the rest of the system is well, needed few new caps, new transistor on the cd player and of course average tape deck stuff as belts and realignment, deck B has massive flutter but i think its a bad slipclutch since its a auto reverse one where it only uses one pinch roller per side
@@SUPERBOBESPONJA1000 your flutter problem might be from the drive point of the take up real slip clutch. I have a Sharp full auto shut off deck from the 1970's and the take up drive wheel goes against the main drive cap stand. However what is not seen is a little tiny rubber that drives that wheel wears away and eventually stopped taking up the slack and the machine shuts off. The other problem I ran into recently was bargain belts from China that their belts are not cut even causing a flutter problem. Now your pinch roller has to be flat against the tape and clean. Often they get a build up in the center making them rounded, and the tape can slip from side to side and if the take up reel is strong, force your tape through faster.
Garod Radio Corp was located in an old industrial part of Brookyn right near the Brooklyn Bridge. The building they were in is now a luxury condo building.
In my past it was Esters' Thrift Shop, that's where I found my first 1V vacuum tube set. An RCA 8BX6 but its a man's lunchbox size. SAMS 44-18. Paid $2 in 1973. No asbestos there either.
My hometown public library had Sams Photofacts but only kept the most current 5 years, due to a shortage of shelf space, according the the librarian. Of course, while equipment did break down before it was 5 years old, the service information was most valuable for equipment over 5 years old. At that age, it often got handed down to hobbyists that liked to breath new life into it.
Same here. You used to he able to go to the downtown library and get a Sams for just about anything. Then library eventually became a hangout for drug addicts and bums and kids to bring their laptops. They eventually moved to a new building and the sams and much of the books got tossed. The library now is mostly a homeless shelter/media center/daycare center now. Last time I went there I saw two bums duking it out in the parking lot while the security gaurd watched them. I just turned around and drove off. The city can't do much about it because it's a PUBLIC library. The library definetly isn't a family friendly place anymore. Not much reason to go either when you can access all the info online anyway
Great E-cap so it's all good. A few good tubes and alignment even if inaccurate for now still works for a 1 Volt tube radio. Leaving it as is was classy Shango. Steve
Those one- and three-volt filament tubes *are* delicate. I found that out the hard way when I was using a tube tester at a local Thrifty Drug and FUBARed a 1T4 when I turned up the filament setting too high.
Great Morning Saturday Shango time. Was looking forward all week for my Coffee with Shango. Always learn something new and really love this channel. One of a Kind channel very enjoyable with learning and humor. Thanks MIke
In the old days aircraft could navigate using a system called An ADF (automatic direction finder) which in voice mode could tune in am radio stations. You would just point the nose of the airplane towards the am radio station (because the stations were usually located within the major cities) and dead reckon towards it.
That was also (part of) the CONELRAD system and the civil defense markings on radios. Knowing that missiles could track stations they would shut down most stations. One station would transmit at the CD frequency, then it would shut off and another would transmit, so they couldn't direction find by radio.
My parents had this type of portable radio with a special feature: the switchover from battery to line cord operation was handled by a relay when the rectifier tube warmed up. So, this was the only instant on radio in the house until transistor radios came of age. Their radio was the only battery/line cord radio that I ever saw that had that feature. Most radios had a socket where you pushed in the plug to switch to battery operation.
It was a MAGNIFICENT video❗️ If you , yourself were an electronic component , to me you are the RECTEFIRE tube❗️❗️ and to all the devices you animate. Hello from Tel Aviv❤
Garod was a good sized manufacturer in the 1930s, but like Colonial most of what they made was sold under other brand's names. Many of the 30s LaFayettes were Garods. They made some high end radios for Lafayette, like 20-some tube count, multiple speakers and chrome plated chassis. Once in a blue moon one of their better sets turns up, but not often.
Sams is still in business, ive bought prints for sets as late as 2005 models from them. They had great prints for the 1990s japanese sets, I bought a shop many years ago and they had the monthly subscription until like 2002, they sent out new prints every month for the previous model year.
At #4:22, about that Vibrator supply..i got an old 1937 Sentinel farm radio years ago, just to understand how that worked. Pretty neat to run a tube radio on nothing but ONE 6 volt battery!
Swinging bar with a magnet on it swung by magnets creating AC from DC = vibrator.. it's kind of like a ringing Bell on direct current it's got a little switch on one side it's off and then it goes back on its own you got the vibrator at a certain frequency and you got it There's more to it than that but that's simply put. There would be coils on the pendulum and the anvil of the vibrator..too
I stumbled upon an interesting radio myself recently. I picked up a Philco 53-1750 "chairside" radio. It's a dropleaf end table with a radio and a record changer built into. Quite an interesting piece. The radio works well, record player not so much. The cartridge hums when in phono mode. Not sure what that could be.
Olá .eu acompanho seus vídeo excelente trabalho dando vida aos rádio vintage eu sou fan de rádio vintage e uma sensação vê um rádio vintage volta a funcionar. Abraço.
that valve line up is quite common in uk radios and that portable style is sometimes called a Picnic Radio because it used be a thing to laze about in the woods with sandwiches (might still be)
Wow, that radio sounds great. I love the looks of it, especially the metronome style dial. And yes, here in Maine there ACTUALLY is a WBLM which plays rock.
People used to remove and insert those 1 volt tubes with the power on and blow 1 or 2 because without the filament load the filter cap voltage would rise excessively. Then a new cold tube applied that voltage to the string. Pop. Thanks.
thank you for mentioning the asbestos issue....I see many of these radios, mostly trransoceanics, that are online in restorations and no mention of the issue is discussed, let alone dealt with to mediate the hazard.
Those battery tube sets with tube rectifiers were probably gentler on the filaments, as they were cold start as the rectifier warmed up. Those with Se rectifiers would have been instant on, and could blow filaments due to surge. Solid state tube might not have motorboated if you'd have replaced a few leaky caps. But leave the SS tubes for those unobtainum tube types.
I have a Garod 15TZ television. It uses a 15AP4 crt. My set is a console version and not the common tabletop TV. Garod was a good brand of electronics.
What an awesome set. Those 1V sets are a bunch of fun. I have a 1939 Firestone S7426-9. Its only got 3 tubes but works really well. I made a power supply for it since it's batteries only.
Yes, Radiotvphononut has come by these 70 year old capacitors in his radio resurrections, and they still worked. Capacitors of today only get 12 to 20 years out of them. Again, your friend, Jeff.
One thing to remember. There are millions and millions and billions of capacitors that have been built over the years. The few that you have experienced on RUclips that have lasted 70 years or outliers. As a rule the more hours the more heat the person in assembly having a bad day all contribute to the life of the capacitor. I have had a few that have lasted way longer than expected, but the majority are bad by this point especially the paper caps. If you want to have a shelf queen with all original parts by all means go for it. I did the same thing with a very early production Regency TR-1. Yeah I could make it play but they don't perform very well when working correctly and in the future how many original examples will be left in good condition?
@@randyab9go188 Exactly, any radio or tv 50 or more years old which still works probably wasn't used all that much. Especially if they have most if not all original parts. Repair shops were common back then for a reason. I have a 28 year old hard drive that still works. Does that mean 90s hard drives last more than a quarter century or was that particular one not used very much..
a leaky coupler cap on the output valve/tube can definitely cause high filament current in lower down valves, making them short lived. the later 25ma filament types are even more delicate and easily blown!
"Он достаточно старый, что бы баллотироваться в президенты?" 😁Юмор этого чувака мне определённо нравится. Помимо его рассказов о реанимации старой техники, конечно.
6:50 "... label in the back that says made in brook-a-leen." - Lou Montey Dominic the Donkey 😂 IF alignment - usually specified to disable the oscillator by shorting the variable capacitor. That removes radio reception. This avoids interference from radio stations with the IF adjustments and possible AGC interference. Adjusting to the IF generator frequency with the trimmers or slugs on the IF transformer with an AC output meter or AC meter with blocking capacitor across the speaker for peak output helps find the peaks. Usually go through procedure twice from last or final IF to first. Use lowest generator signal possible to give adequate reading or indication. Tracking is the state where the oscillator runs at the frequency that tunes the stations reasonably close to the dial indication and the antenna input circuit is also in tune as close as possible. Oscillator coil tuned at low frequency about 600 KHz. Oscillator variable capacitor trimmed near 1600 to get the tracking per the dial scale on spec. Then the antenna side input circuit (usually larger or more fins on variable cap)is done around 1400 KHz to get the antenna circuit tracking with oscillator. Steps are often repeated two or three times. This is the basic theory as I understand it. Beyond this point there are sometimes padders to be adjusted, moving coil windings and spreading or compressing variable capacitor plates. There are procedures that require rocking the variable while adjusting usually around 1400 KHz. An old fashioned fluorescent light can be used for basic trimmer peaking, but generator needed for these additional steps. These are steps that I don't completely understand except to say this is how to try and be sure there is proper or at least optimal tracking alignment at the top and bottom of the dial are obtained again by getting the oscillator and the antenna input circuit to tune together throughout the dial range. Oscillator picks the station frequency and that's absolute. Then the antenna circuit peaks the signal for that station which starts the selectivity process and helps to reject the image frequency. You can peak a radios RF tuning to a particular frequency and sometimes to dramatic effect. However you may find other areas of the band to be very insensitive or 'deaf' or possibly have oscillations or 'birdies.' I should also say that this can be done without a generator as long as you have weak stations at the low and upper bands. If your radio sensitivity is low at the start you can use stronger stations. Peaks are difficult to identify if AGC is reducing gain while adjustments are being made. Very old radios may have plate voltage on the adjustable IF capacitors so use a wooden adjusting tool made from a wood dowel or kabob stick or plastic alignment tool. If they're stuck the power the radio off and try to loosen first with a metal screwdriver. Ok! That's the best I can do. I've wanted to comment about this for some time. Good luck!
You really don't have a nice word to say about any radio, there all works of art in there own way, also you could try restoring one instead of just getting it going !! There worth it .
When using different replacement circuits, such as solid state tubes, it would be the best to rework the circuit around the part. Solid state most likely is faster or more sensitive and will oscillate . Some extra low pass filter and/or shielding would most likely help. With most equipment, no one will really look inside, so I often just replace entire portions of some circuits (solid state 1970's/1980's) even with extra addon PCB's. I don't want to pay some really inflated prices for vintage ICs, when a cheap modern part will happily replace that at fraction of the cost. Also you can fix certain shortcomings of the original design (rationing parts in the soviet bloc).
The local JC (late 70s) had Sam's folders from about 1-1,500. it had an electronic technicians course and in the basement they had a set of Sam's that I suppose they taught TV service from. I loved to go in and just thumb through and look at some of those old ones. I'd imagine the whole set was retired to someone's collection and hopefully not just dumped. In my personal collection now I have 11 through 100 and a few other bound volumes up to 350. Someday I'll find 1-10.
Years ago I found a Garod Radio at an auction. I the radio was made in the late 40s if memory correct. Anyway It was one of my first radios I tried to repair and it's almost done just need to patch the speaker as dummy here thought he should put his finger through cone.
....now add an FM tuner/converter and its set to go for another 75 years 🙂 I am surprised the solid state tube man has not yet released a plug-in "mixer tube" with an on-chip FM tuner which utilizes the L.O. circuit...
That is such a COOL 😎 radio. Too bad ya couldn't carry your lunch to school in it. It's an old tube type radio. The speaker is probably field coil, but may be permanent magnet 🧲. Your friend, Jeff.
@@brigganthewolf1461 In battery operated radios they would use PM speakers, you don't want the power in a field coil to eat up your batteries. And AFAIK PM was starting to become much more common in AC-powered radios by then.
Tricky low voltage tubes, love to burn their filaments. But so many old tube sets are at least 70% working or better. It's the plastics, metal and other physical stuff that starts to fail before the electronics.
I didn't look at the schematic for this one but battery radios often have a resistor between the negative of the battery and ground to generate a negative bias voltage for the output tube. It's the exact same idea as an AA5's 150 ohm cathode resistor.
Wow, man when they built that, they built it to last, and last it did! I am amazed, wish I could find one of those to play with myself but the recent demise of our side by side and the loss of a months worth of food put the purchase of toys on the back burner. Thank God Social Security refunded me the money that was in mom's bank when she died, it was just enough to cover the new fridge, a plane old fridge, no ice maker or water dispenser like our old unit had, I will miss that but the cost was prohibitive, the SS refund was just enough to cover the replacement. Somebody up there loves me I guess.
Any plans to make those SAMs pages available for download? I don't even mind paying for them. Just that most sites charge $30 apiece for them, making the schematic the single most expensive part of most restorations. Assuming you don't have to buy some expensive tube of course. I have the Rider books, but a lot of stuff isn't in them.
The screen on the generator didn't register your touch correctly and set it to 445khz instead of 455khz which is frustrating if that caused some of the issues you had aligning the tuning capacitor.
Nice radio. I have to get to work on my own battery radio that is dead quiet. Since the tubes are so delicate (and expensive), what do you think would be best to preserve them? Dropping resistor on the line? AC line voltage these days is 120 and these radios were designed for 110.
It could run for president. Anything is better than the current dim bulb 💡
AMEN Brother !
Mind blowing that the filter cap was still really good.
Did anyone else notice that he had his sig gen set to 445 KC instead of 455 KC? That is why he had to tweak the IF a bit. Not that it really matters all that much.
I wondered that too - I bet it would be more sensitive at the right IF
41:12 for timestamp
He could set european 465 kHz IF also. Nothing dramatical.
Really I might have to go back and revisit that. The most important thing is that they're in a line
@@shango066 I dont think being off 10 KC in absolute terms is going to make any difference.

IF alignment - usually specified to disable the oscillator by shorting the variable capacitor. That removes radio reception. This avoids interference from radio stations with the IF adjustments and possible AGC interference. Adjusting to the IF generator frequency with the trimmers or slugs on the IF transformer with an AC output meter or AC meter with blocking capacitor across the speaker for peak output helps find the peaks. Usually go through procedure twice from last or final IF to first. Use lowest generator signal possible to give adequate reading or indication.
Tracking is the state where the oscillator runs at the frequency that tunes the stations reasonably close to the dial indication and the antenna input circuit is also in tune as close as possible.
Oscillator coil tuned at low frequency about 600 KHz. Oscillator variable capacitor trimmed near 1600 to get the tracking per the dial scale on spec.
Then the antenna side input circuit (usually larger or more fins on variable cap)is done around 1400 KHz to get the antenna circuit tracking with oscillator. Steps are often repeated two or three times. This is the basic theory as I understand it.
Beyond this point there are sometimes padders to be adjusted, moving coil windings and spreading or compressing variable capacitor plates. There are procedures that require rocking the variable while adjusting usually around 1400 KHz. An old fashioned fluorescent light can be used for basic trimmer peaking, but generator needed for these additional steps. These are steps that I don't completely understand except to say this is how to try and be sure there is proper or at least optimal tracking alignment at the top and bottom of the dial are obtained again by getting the oscillator and the antenna input circuit to tune together throughout the dial range. Oscillator picks the station frequency and that's absolute. Then the antenna circuit peaks the signal for that station which starts the selectivity process and helps to reject the image frequency.
You can peak a radios RF tuning to a particular frequency and sometimes to dramatic effect. However you may find other areas of the band to be very insensitive or 'deaf' or possibly have oscillations or 'birdies.'
I should also say that this can be done without a generator as long as you have weak stations at the low and upper bands. If your radio sensitivity is low at the start you can use stronger stations. Peaks are difficult to identify if AGC is reducing gain while adjustments are being made.
Very old radios may have plate voltage on the adjustable IF capacitors so use a wooden adjusting tool made from a wood dowel or kabob stick or plastic alignment tool. If they're stuck the power the radio off and try to loosen first with a metal screwdriver.
Ok! That's the best I can do. I've wanted to comment about this for some time. Good luck!
Well, that is interesting. I never considered you could build a collection by just flipping thru Sams guides. That’s really cool!
Is that steak knife from Craftsman or Snap-on?
Awesome Video Sir. Cheers!
You really don't have a nice word to say about any radio, there all works of art in there own way, also you could try restoring one instead of just getting it going !! There worth it .
That is a COOL RADIO ! I like the look of it as well.
77 years old and still running? A lot of us are. Still.
Just think Shango, how long this radio was on earth before it came to you. Wow.
When using different replacement circuits, such as solid state tubes, it would be the best to rework the circuit around the part. Solid state most likely is faster or more sensitive and will oscillate . Some extra low pass filter and/or shielding would most likely help.
With most equipment, no one will really look inside, so I often just replace entire portions of some circuits (solid state 1970's/1980's) even with extra addon PCB's. I don't want to pay some really inflated prices for vintage ICs, when a cheap modern part will happily replace that at fraction of the cost. Also you can fix certain shortcomings of the original design (rationing parts in the soviet bloc).
The local JC (late 70s) had Sam's folders from about 1-1,500. it had an electronic technicians course and in the basement they had a set of Sam's that I suppose they taught TV service from.
I loved to go in and just thumb through and look at some of those old ones. I'd imagine the whole set was retired to someone's collection and hopefully not just dumped.
In my personal collection now I have 11 through 100 and a few other bound volumes up to 350. Someday I'll find 1-10.
Yeah scanning stuff really is tedious work, thank you four taling the time
Beautiful interface.
Amazing it works. Expected it to go up in smoke, but nope!
Years ago I found a Garod Radio at an auction. I the radio was made in the late 40s if memory correct. Anyway It was one of my first radios I tried to repair and it's almost done just need to patch the speaker as dummy here thought he should put his finger through cone.
Love the 'pyramidish' shaped tuning dial to appeal to the Freemasons.
" In Garod we trust. "
1T4, Alfred Morgan's favorite go-to tube...
Battery placement, deep yes but nowadays it would have said do not ingest batteries.
....now add an FM tuner/converter and its set to go for another 75 years 🙂 I am surprised the solid state tube man has not yet released a plug-in "mixer tube" with an on-chip FM tuner which utilizes the L.O. circuit...
42:00 - you're aligning it to 445
Dial cords are evil !! I used to cheat. Many were available OEM pre made
with end loop & spring. Just slap it on.
LFOD !
Brilliant little /big portable radio
I'd like to know who was the exterior designer?
Nice work as always Master shango066
That is such a COOL 😎 radio. Too bad ya couldn't carry your lunch to school in it. It's an old tube type radio. The speaker is probably field coil, but may be permanent magnet 🧲. Your friend, Jeff.
Schematic in video mentions PM speaker. Not EM. Fairly unusual for the era.
@@brigganthewolf1461 In battery operated radios they would use PM speakers, you don't want the power in a field coil to eat up your batteries. And AFAIK PM was starting to become much more common in AC-powered radios by then.
Garod dog that's a nice little unit.
Make sure you punch a hole in the speaker. Oooh been there done that unfortunatly!!
Is it possible to disassemble a wax capacitor and throw in a modern one making it look original but repairing it at the same time?
Yeah but those people who do it need their heads read. I mean would you re-stuff the oil filter on your model T lol
It might be easier to build a paper capacitor, print graphics on it. Over time you get proficient at it.
The persons who built that is no longer with us.... Amazing stuff...how it is still with Us the same with music 🎶... Wow
Where did you get those?!
That AirRad schematic...
Tricky low voltage tubes, love to burn their filaments. But so many old tube sets are at least 70% working or better. It's the plastics, metal and other physical stuff that starts to fail before the electronics.
Looks like that 270 ohm resistor on the B- battery was placed there to sell batteries? Is the battery B+ tied to ground?
I didn't look at the schematic for this one but battery radios often have a resistor between the negative of the battery and ground to generate a negative bias voltage for the output tube. It's the exact same idea as an AA5's 150 ohm cathode resistor.
It works ok, I'm sure you can find another volume knob.
Wow, man when they built that, they built it to last, and last it did! I am amazed, wish I could find one of those to play with myself but the recent demise of our side by side and the loss of a months worth of food put the purchase of toys on the back burner. Thank God Social Security refunded me the money that was in mom's bank when she died, it was just enough to cover the new fridge, a plane old fridge, no ice maker or water dispenser like our old unit had, I will miss that but the cost was prohibitive, the SS refund was just enough to cover the replacement. Somebody up there loves me I guess.
117z5 was also used in some Zenith Transoceanics. I believe the name Garod is prounanced the same as Jarod as in the jewelers
You mean garrard the jewellers? Like the turntables? (They used to be the same company)
Pronouncing that with a J is an American thing
@@robturner3065No, theres an American jewelers called Jared. I'm a Canadian with British roots and I'd pronounce Garod like that.
@@FranksPlace-jk7pj thanks, not heard of them
I think it is beautiful !!
31:34 Blazing Saddles 😂😂
So fun. Glad to see a minimal restoration with a huge impact! Too bad the knob fell apart. Was it ancient Bakelite? Happy Saturday 🙂
Bakelite would not have deformed like that.
Any plans to make those SAMs pages available for download? I don't even mind paying for them. Just that most sites charge $30 apiece for them, making the schematic the single most expensive part of most restorations. Assuming you don't have to buy some expensive tube of course. I have the Rider books, but a lot of stuff isn't in them.
My recollection from deep in the past is that "Garod" was pronounced with two distinct syllables. That is, as if it were "Gar-odd".
Company is from Brooklyn, NY but this was made in Newark NJ.
The screen on the generator didn't register your touch correctly and set it to 445khz instead of 455khz which is frustrating if that caused some of the issues you had aligning the tuning capacitor.
Those cans are always off, meanwhile tuning it to 445khz xD
Nice radio. I have to get to work on my own battery radio that is dead quiet. Since the tubes are so delicate (and expensive), what do you think would be best to preserve them? Dropping resistor on the line? AC line voltage these days is 120 and these radios were designed for 110.
If the filaments are in serial string, count the total filament voltage and use zener diod just 1V higher value to protect them.
