Start by checking voltages and AC ripple.  These logic circuits require that the voltage is spot on and clean.
 Also change out any electrolytic capacitors.  At times I have seen the inductors on the counter board go open.
They look like little resistors.

I saw your pm today. Been very busy here.
I have yet to get back on working with one of these.  Sometime in the future when time allows.

Hi Steve and welcome.
Nice setup and at times we have to do the best we can.
HF mobile can be quite fun. I had a TS-140 and home brew HF antenna and had a great time with it.

Thanks for sharing the videos. I added the directs to the videos in your post. I really need to get the youtube links to work by user uploads.

I may have that manual. Will look this coming week end.

Good question. If you pull of the specs you can maximum current draw.
The filaments will draw about 150ma when first powered up, and total will be around 30 watts of power. this is near 4 amps. So a 5 amp fuse should be ok.  I like the fuse before the switch. Remember switches and short also.

Doing a restoration is not as easy as I thought. have run into some setbacks but am still going forward. had a broken knob on one of the rotary switch's and did some searching for a repair option. found a youtube video
that addressed the problem . cloning vintage knobs Wesley Treat's channel had this video.       10 min. video was very cool had some things to buy but the quality of the repair and the "original " look it gives right down to the small scratches was very impressive  for the do it yourself kinda person.

I agree, restorations can really be tough at times. Finding and recreating vintage parts are near to impossible.  Why I never throw out old electronics.

That was an excellent video. Thank you for posting it. I never seen that one. His style is fun to watch.

Thanks Chuck. Always something lurking in these rigs.

Cool deal.  I think I have seen a schematic for that model. I will have to dig around.
I will get in touch with you today on the board. PM me if you do not hear anything. So busy.
