Note on Audio. Guys I am trying out a new sound system with external mics. In the intro I had the sound system running. I was using right channel only audio. Once the video started, I was running both channels. I have already shared this with Patreon members and will be testing throughout the next few videos. Please comment on the audio quality.
Hey bud I really enjoy your work and videos. I'm reaching out to you about the IC 745, I did the am mod UF the radio swings backwards when modulating. I was wondering if you could help me out on am power adjustment mod?? Any help would be appreciated!
@@jessewhitten44 Do you have the carrier set to about 20 to 25 watts?
@@TheRadioShop I have the potentiometers in the radio set so when you adjust the variable knob on the front of the radio it will go down to 10 Watts and go up to 100 watt but it seems like no matter where I set the dead key is still swingings backwards.
The "boring" stuff is often the most important stuff! Even though I don't have one of these rigs the principles apply to lots of other equipment...TNX Buddy! 73 - Dino KLØS
That is true Dino. Sort of like sitting in a lecture. 73 and thanks for stopping in.
Hi Buddy. Thank you for making and posting another fine well thought out and nicely presented video. Your audio sounded great... It was so good I never gave it a thought until you asked for comments... had to go back and listen to some of it again because you asked.... I have TWO FT-101E's. One that was purchased new in 1976. It hasn't been powered on since 1998. The second I inherited a few years back. The original owner purchased it new around 1979, used it for a couple of hours and then put it back into it's original box to be kept as a spare... and was never needed. So it hasn't been powered on since 1979 (ouch... over 40 years) ! I have bought a complete set of electrolytic caps for both so far and am working on getting the mylar and mica caps I likely will also need. I try to watch all your FT-101 videos... even if not pertinent to me, I find I often learn something new. Always a good day when you learn something new! Your videos are a fantastic source of tips on my upcoming work on my 101's... I found myself even taking notes at some points! ...almost like being back in school ! THANKS AGAIN, I am grateful for you sharing your knowledge.
....
BTW... wondering... as the tubes haven't been powered on for so long... might I consider perhaps pulling them out and only powering up only the filaments for a while (hour or so) before powering them up inside the radio ? That is... if tubes have not been powered on for an excessive amount of time, is there a process to use to safely bring them back into service?
Rick, Thanks for sharing. Sounds like you got yourself some nice rigs, I also appreciate the kind words. Yes I have done that with vintage tubes, mostly the glodbe style tubes like you find in 1920-1930 era radio. I jusr mount a socket to a board, plug in the tube and apply filament voltage and let it soak in for a few hours while cycling the power a few times. I even done this to other sweep tubes like 6Lq6 tubes.
I just purchased a 101 EX and I already had a 101 FX for decades. I’m going to use this set of videos to go through each one (lucky I’m a tech), re-cap , clean and adj where nessecery. I love that you filmed this.
I literally took mine apart as you did and followed your guidance step by step. This sort of video is very handy to use as a guide. I’d love to watch you recap the capacitors and see how you do it.
We're going to have to start calling you Dr. Buddy. Chief Forensic Examiner and sometimes Crime Scene Investigator of the FT-101 and other radio series. You sure have fixed your share of crime scenes in these radios over the years. It's not boring at all. Just a nice methodical approach to servicing this type of radio from somebody who has done many of them. Everybody benefits and learns from your experience. Keep on going Buddy. 73 Doug.
Thanks Doug for those very kind words. It is guys like yourself that keep me going.
I have recently refurbished a 101 and a 101 e and I couldn’t have done it without your videos many thanks for sharing your knowledge.
This is one of the best engineered radios yaesu have ever made and a pleasure and education to work on.
Thanks Tim. Glad you were able to work through them. I love these old rigs.
Great video Buddy. Not boring! That stuff is just as interesting as the testing and repairing stuff. Love when you include it. 73 de kb7ici Bill
Much appreciate the comment Bill, Thanks
Best FT-101E vídeo on youtube. TNX, Buddy fer all. 73 from Juan, EA7JTT.
Thank you very much
Well This is exactly what I need to repair a couple FT-101E that I have. Very interesting and not boring. So many of these radios still around and on the air. I think every ham operator here has one or two sitting in a corner. Thanks Buddy and will be watching for the alignment video with much enthusiasm. One of the greatest radios ever made.
I agree Lyle. These radios have a special place with me. Thanks for the comment
Great stuff Buddy. Thank you for sharing your knowledge on this particular transceiver. Audio was good.
Thanks, my pleasure. Appreciate the audio report also!
Wow Buddy, good to see your face and good job getting this old 101 going...i had a 101E back in the day and totally regret getting rid of it....will be watching closely
WD8JM
Thanks Jeff. I hear that a lot when folks get rid of these.
I learn something every time I watch your videos Buddy. I'm going to dust off my old 101E and start working, soon!
You can do it! Thanks for watching
Those are an absolutely classic set but they are getting hard work regards maintenance after all these years. Watching you work is always a master class. Thanks regards Chris n
Thank you very much Chris, always good to see you!
I have one of these that I am working on...so this vid was very helpful...thank you. I do no like that protective plastic on the front makes the radio look SO cheap..took it off of mine as it was yellowing...looks so much better! :-D
Yes when it turns yellow has to be removed. Makes the rig look bad. This one is very clear.
I love this kind of video, very helpful! Thanks so much!
Thanks Andrew
Thanks buddy. Giving a vintage rig a good eyeball is on top of the list for troubleshooting in my shack after a good stiff. :)
I've had my EE for so long now I don't remember what year it was when I got it. I want to say 1989 or 90. It's been a great radio and I have yet to have to replace anything in it. It's 100% original and has been in use almost daily since I got it. These days it's just a listener though since I have yet to find a suitable antenna for an apartment that doesn't allow them. Being old and poor limits my choices but for now the mess of wire I have running around my living room ceiling gives it somewhat decent reception. I've had many offers for it. I think it might be time to pass it on to someone who can talk with it.
Even though it's turned on almost every day I imagine it needs new caps and some other work done but it's almost spotless inside and the knobs turn freely. I have done my best to do some maintenance on it over the years but have never needed to replace any parts.
Thanks for sharing. I have seen these that are in use last for many decades. I have talked with many hams running ceiling mounted antennas.
Thank you for making these vintage radio videos. I'm going to see if I can make my ft101e work again by carefully observing your interesting instructions
Audio is Excellent!…Great video as always
Thanks
Steve

Awesome, thank you!
I found it interesting and informative Buddy, I have a 101EE that I have been trying to get the parts for before I start on it and it's a radio that I don't need up yesterday so I'm just taking all the time I need to try and do quality restore thankfully who bought from at a ham feast told me things about that by time proved him wrong I walked away with it $50 (This Radio was my first love :))
Good score on that one Douglas. Thanks
Always a treat Buddy! Thank you for all you do. Cheers!
And thank you for watching
Another great video Buddy. I have managed to watch all your videos, some twice! keep up the good work! (ps) the longer the better...
That is a lot of hours my friend!. Thanks
Thank you for this as it is full of good info. Keep at it Buddy!
Appreciate that Mike
Great upload Buddy, thanks very much.👍🏻🇬🇧
Thanks
Hi Buddy,
I enjoy all your repair videos. Have been looking for the user and service manuals for my FT901. I made some changes to the receive filters that were suggested from the Fox Tango group and made notes of them in the manuals. I did buy their CD with all the newsletters and found the ones for the 2.1kHz 8 pole receive filter upgrade. You and the family stay safe. 73 WJ3U
Thanks for sharing Don. The manuals for the 901 I downloaded were very poor quality. Always good to find an original print.
Appreciate your Work and style. Oxidation on printed circuit conductor-streets are best removed by
a fibreglass pencil like "staedtler" with replaceable brushes.
Theese wer used by engineers to erase faulty drawings in technical drawings back in the seventies....
The fibreglass pencil is also ideal to clean contacts, alternators etc. without abrasive damage to
the cleaned device.
this was not boring at all to me, it reminds me from when i used to repair the ft101 line and ts520 line in the 90's. You touched on every issue i used to find myself, keep up the great videos, i enjoy them much.
Thank you very much.
Excellent video! I've just got a 101E in excellent shape. No parts are missing and no mods; just like it left the factory with the QC tag still attached to its carrying handle and the front panel plastic protective sheet still in place. Everything seems to work fine except the 28.0 to 29.0 bands. Its XF-30C CW filter and the re cap kit are on their way ...Cannot wait to start working on it...
Thanks for posting!
Hi Buddy, I'm following from home and doing the exact process you demonstrate for a FT-101B that needs alignment and neutralization also. It's not too bad shape and will re cap as I go.
well,what a pleasure to see a technician keeping OLD tech books,manual about old radios.
i am buying and old friend back,FT101E and will need some books,and even if i am not a tech i just want to
know what boards,parts are!!
i love these old radios,i have an FT100D all electronics made and dont like it.i will go back in time according to friends and,,,,i love it.
73/s mister and keep them in shape

Well, s special treat tonite. In all the years of watching, I'd never seen you in front of camera. Great vid....am looking at my 101F as I follow along .. TY
He's been on camera numerous times...
@@buildstoys well maybe so, but not in the ones I've seen so a treat for ME.
Thanks Ernie, I do not show my ugly mug that much. But was not the first time.
Great job again learned a lot thanks for taking the time to share with others. without you it would so much harder and may not do as well. God Bless
Thanks for your kind comment Mike
Really interesting stuff, Buddy … to me ! I have a FT-101 and FT-101B that I’ll be restoring soon, so I’ll be following this series with great interest. 73, Jamie WB4YDL
Sounds great Jamie, keep us informed on the process.
Wow... that radio is built like a tank. Very interesting stuff and great tips on the inspection process. Thanks Buddy. Love watching your work. 73 de K7RMJ Frank
Appreciate that Frank. They are quite nice rigs and built to last.
good tip about the AM filter and that it requires a mod to work
Great walk through Buddy! Enjoyed every single minute and looking forward already to part 2!! Love watching you work through these collectible transceivers! Thanks for sharing!!
Thanks Scott. Glad you enjoy them.
Thanks Buddy, real interesting stuff. I'll be following the rest of the series and I'm really looking forward to the TS-520 in depth so I can pluck up the courage to go in and refurbish mine. And your audio sounds fine
Thanks Alan. The 520 is fun to work on also. Not quite as easy as the 101 but still fun.
Thank you for doing this! This is an encyclopedia for FT101 lovers taught by a masterful professor. Rock on Buddy. Looking forward to that transmit and receive alignment. All the best brother
Thanks for the kind words and watching.
Tnx Buddy, the FT 101 used a interesting line of transverters i used the FTV 650B.,
Much appreciate your series on this unit. Been wanting one of these for a while and just acquired one. I want to go over the unit completely , and it seems you will be going over most things I need to.
Thanks for the video Buddy
Thanks for watching Bill.
To replace the FETs I used 3SK40 and 3SK45 that are pretty cheap from Ebay. All the leaking, bad gray electrolytic caps and cracked mylar caps were replaced with assortments from Amazon.
i always love your videos and i learn alot and thank you!
You are so welcome!
Not boring very enjoyable
Thanks terry
Thanks for the video
nice workbench and equipment!
It's possible the HF-IF board may be correct and a different shield with sticker was installed during a repair. Guess you will find out soon enough. Looking forward to the next episode. Thanks Buddy.
Honestly, anything is possible with these units. Just about seen it all. Great comment.
I did the same with a Kenwood ts 830. Works great. 73s
Good deal Bob, thats another classic!
Hi Buddy, I'm glad I found your channel on RUclips. I got an FT101EE from a local ham that is real sick. I told him I'd get it back on the air. Are you doing repairs? If so, I would like to engage your help. Thank you,
73, KK7EMW
Absolutely wonderful video. I just picked up a beautiful FT-101E and purchased the cap refurb kit. Thank you for showing us how to remove the boards in such as easy and safe manner. I am also curious if you work on other's FT-101E's? How can I contact you? Thank you!
Great videos Buddy, very informative, I enjoy them so much I decided to go out on a limb and bought an FT-101B. It receives great but doesn't transmit. Nothing happens when I key the mic or put it into MOX. The relay seems ok, would this condition happen if C13 is bad? I'm planning to replace it either way like you recommend. Any recommendations on where to start would be greatly appreciated. Thanks Buddy.
This seems like an INCREDIBLE amount of work to recap and check all the resistors. How much time does a full recap and run-thru/alignment/tune-up take?
You mentioned you were going to do a tutorial on making new lettering for old radios. What video was that? I cant seem to find it.. Cheers!
Thanks for the video,,, If you have one that is so dirty that you think the only way to clean it is using a I pressure power wand what would you recommend on how to deep clean it.
I'm talking like forgetting it was under a table for 6 months and it had my bench grinder over it.
Thanks
I have to pull mine out sometime and try to rebuild it so..lol.. Was told I may beed a board because according to one guy, the Customs in UK cut the board or wires..lol
Been watching your videos on the 101E. So far, My unit is pretty much untouched. The only thing is on the 1314A regulator board. The MFC6034A has been removed and they put an SK3669 in the 1,2, and 3 position. The 4,5, and 6 positions are unpopulated. None of the other components in that section were changed. I think there's a better solution than that.
QUESTION:
Any ideas on the best route to go changing that?
I know that the earlier units used 2 transistors to regulate the 6v for the VFO.
Hi Buddy, did you say you normally buy individual components, and not the kits? 73, KM5L
I found a Kenwood TS 520 Can I please ship it to you and have you go over it completely and fix what needs fixed? Thank you.
Damn ! That’s a lot of electrolytics being thrown away that could be used for a nice fun video of them blowing up 😝😝
What is the correct lamp for the signal strength meter illumination. God bless, Bill (G6ATO)
Thx n4jrs 73
Thank you
looks like i might be following the videos and doing the same things to my FT101. Your S/N was 200533 but you state it's 200533 then later 20533, my one is "82J 127019" which to me is 127,019 which does not fit with the list shown. or is it 12,701.9? How do you decode the serial number please.
EDIT - Just found that the last 5 digits are the serial number, so does that mean that yours is Sn 00533?
Yes I messed up on the SN. I think yours is August 1978. And yes that is correct.
What is that 5 W Resistor mentioned on 32:30 second, Mine started smoking and had to shutdown the unit. I believe it is R40 a 1,5K Ohm 5W Metalic Film resitor, but I replaced it with another 1.5KOhm and got burned as the moment I turned the On Switch on. Will need to trace all my circuit down . This is my first radio I got 1 month ago, receiver works just fine... Output never tested it. it was working fine, after some initial brief and cautious tuning, I got the smoke coming on. :(
By The way thank you for all these videos!!! Extremely helpful in getting to know , clean and recap my FT101-EE unit.
How do I get in touch with you. I wanted to see if you would work on a palomar vc 100
where do i start if i find swapped crystals?
I'm trying to find on any of the FT-101 schematics,(the older and "the latter"),the 10uF/315V electrolytic cap installed on the 5.1K; 18K voltage divider (2nd grid of V1)... I cannot find it ;it seems it is a mod which was added latter...
I dont think it was ever shown on the schematic
@@TheRadioShop I finally found it on a "latter" FT-101 schematic... C151... I choose not to replace mine with a new cap.; I just removed the shorted C151 cap I found in my FT-101E .The rig works great without it and there is more space around those power resistors. I replaced the 18K /5W which was open with an 18K/9W...
If the markings for the tube is etched, then isn't that GE? Regardless of what the tube says, etched markings are supposed to always be General Electric.
I have heard that many times. Not sure if it is both the supply and tube designator of just one. As this one tube surely has Sylvania on it(painted)
@@TheRadioShop I think it would be the manufacturer who puts the designation on the tube, and then the buyer puts whatever brand they want on it. So if the tube number is etched, I would be inclined to think GE manufactured it for Sylvania.
Not that it matters too much. both GE and Sylvania tubes are fantastic.
Where can I get a power cord from many thanks Barry G4DIP
WHAT IS THE BIG DEAL WITH THE YASEAU 101 series of radios? Clearly fine radios but I bought the Drake T-4B/ TR4X twins, in the 70's, for $250! It was compared to the Colins pigs. It's the best receiver I've ever heard.
Where can I buy a power cord from I need one very badly, this is Barry G4DIP many thans
Barry, I do not know of anyone that sales the complete power cord. Once in a while one will turn up on eBay. What I do is buy the connector (variuos places like eBay) and wire in a computer style cord. You will also have the add jumpers but all this is in the manual. Word of caution; most of the connectors are numbered differently than the original Yaesu connector, just wire like the diagram in the manual shows.
i looked up a 12yb7. should be a 12BY7. then i zoomed in. 12BY7
Yep, I have that problem of seeing one that but saying another lol.
@@TheRadioShop yeah its called dyslexia, or so they say. i transpose letters and numbers all the time and i get in trouble at work for it. im surprised i caught the 12by7🥴

@@jrumiano the first 3 or 4 minutes after the music while he was doing some sort of intro on camera was dead. It came back on after he started in on the radio. My computer is working ok.
@@jim874 For me the first 1 1/2 minutes there is audio in the right channel only. Then rest is in both channels. You must be listening to left channel audio only.
Jim, As others mentioned the intro was done in right channel only. I am trying out new audio gear.
@@TheRadioShop Right! After someone told me that, and I said I was receiving in both channels through a Stereo amp, I did a sound check on my gear. Found a soldered connection that was not soldered. Well it WAS soldered , I thought at one time after I replaced blown up speakers. Once re-soldered , It worked ok when I went back and replayed the intro.
