Hi Todd. I have a TS-830s that needs to be worked on. I was hoping if you can work on mine. Thanks!

This is so cool. You are the man. Acetone does cut the varnish when heated. Just a thought.

What was final solution after adding semiconductor diodes ?

Hi.... I have a 901DM on my bench and the clarifier does not work. I can't hear the relay open/close when I push the RIT button in. TX clarifier does work. Question! How in the hell do you get to the 1920 switch board? Do I have to take the entire front panel off?

Hi Todd, can I get the model number of the AM/FM Tuner box?

Yes great stuff and so small Thanks for sharing It gives me an idea that things can be fixed with time and patience.

Congratulations God bless you greatly I hope you are better soon hugs

Nice and neat , thank you very much .

Great video a great learning experience for those who don't own this radio. Enjoyed it very much appreciate your doing this video very kind of you 73s Mike

You are THE 7603 MASTER

I am interested in building one and was wondering if you could provide me with a parts and source list. I would greatly appreciated it very much.

hello i just got rid of mine,very scratchy and noisey.i wished they did all the old stough again best ever made

These set have usually a lot more than a problem... piece of junk now.

Thanks very much for this series. Very interesting and well explained. I've just bought a TS830 and also have a TS530, so of particular interest to me.

Yup, you need to adjust the pre-selecter to the band you want, you'll get no audio out until you do this. This caught me. I just got one of these, and re-capped it. 73

Great video, lots of good info, especially the VFO servicing. My 901DM is 46 years old now, June '78 build and the VFO is getting a bit lumpy. Also got issues tuning up on 40. Loading control won't peak. Just keeps rising all the way to position 10 on the scale. l hope yours is now working 100%. Thanks for posting. 73 de Keith

I bought one FT 910D back in January. Seems the Attenuator Switch is pretty much broken. If it is half depressed I have a good reception, in any other position I have nearly no reception. And the S-Meter doesn't display how much output I have. I will trace all the cables and see if I can get the 901 back to service. On the good side: VFO is stable and not drifting, dial is smooth output is around 80Watts, but without a proper readout I won't try more. Any tipps are higly appreciated.

These Ft-901s were the top of the line radio in their day. I’ve been running one as my backup rig for a few months. Killer receiver and rejection filtering.

Great to see the vintage units I longed for in the late eighties early nighties. Hope to see part 2. Regards steve

Gotcha! 🙂

I bought one at a good price. I am thinking of using banana plugs so I can use different cables, however, I see on lines are grounded. Not sure how that will work out. I might test before committing.

Nice video. Learned something. I was wondering if the M (memory) enabled might something to do with digital display. Looking forward to the follow up. Fernando N2FQ/6

I really enjoyed this one , especially seeing the VFO. And 720p is back! Thanks.

my qyt-KT8900 microphone works perfectly

Why the low res?

How did the battery pack work out? (You are braver than me.I would be afraid of burning my place down.)

great work!

Must be nice to be wealthy.

interesting

Great video ! Thanks for the effort and looking forward to more of the same.

I posted a long comment with a lot of helpful tips. I did not include any links. Even still, YT deleted it. IIRC, you can list me as some sort of a preferred commenter and I can post it. If you care to do that.

It looks like next to adjustment R741 up by your high voltage oscillator, it’s stamped “1675v ADJ” which would imply that the 1665ish volts you were measuring were actually very close to correct. It’s odd that the schematic calls for over 2300 or so.

When I was a little kid in 1962 the next door neighbor was listen to all of that stuff and amazed us kids when we used to go over and watch him work on that stuff

Not surprised that it had so many issues given its age and apparent condition. Thanks for the troubleshooting tour.

Yes, drill it out.

Freudian slip. 😅

You R the "RF Whisperer" Just saying. Thank you for the detailed walk-through. Cheers from So.Ca.USA 3rd House On the Left. p.s. I noticed I'm subscriber 666 and I have to be honest, should I be worried? Ah... I'll risk it

Thanks 👍

Lovely old radio.

Hi, It would be great if you could make a video showing how to align the receiver. I don't have a lot of test equipment but would like to see how it is done. Thanks

I enjoy your videos but wonder why the video resolution is just 360. Is this the limit of the camera or a bandwidth issue? Thanks!

Coolio; listening on my Allied 395 receiver. *THumbsup*

just picked one of those up at a hamfest 40 dollars nice little repeater at that price

Thanks for sharing your knowledge with us.

I so enjoy your trouble shooting skills and showing us what you''re doing. Thanks so much!!!!

Suggestion... I do not have solder tweezers, but you might try using them to hold a piece of solder wick to mop up solder. Might be better than fumbling with holding everything by hand and getting burnt fingers, which I do. If you try that, please let me know the results.
