I'm trying to bring one back from the dead. There are no schematics available that I can find.   I know its a shot in the dark but if anyone has one of these, could they please peek inside

theirs and tell me what component was in the spot where i circled in red? I would be eternally gratefull. This part is located on the little circuit board on the side.

I was hesitant to post that because I thought maybe it was you. Sorry. Wish I could be of more help.

I've got one, but I don't really feel very motivated to pull it out and open it up.

 

I can be 'encouraged' with fine wines, caviar, Wagyu steaks, rare car parts and plain old cash....

Top marks for taking the trouble to tell us that though.

Model number of the unit? Any kind of identifying markings on the circuit board - like a part number or assembly number?

Well you made me go a little further than I would normally go on a first date, but here's what I saw inside:

Thanks Alan, the pcb looks like the same model as mine cts-2000zd. I've noted differences between the earlier model that Kats posted a picture of and this later one.

Mine is a Hitachi CTS-2000Z (without that letter D suffix that's on yours?) which was fitted as factory stock equipment on one of my Fairlady 240ZGs in early 1972:

I think it's safe to say that electronics are not my specialist subject...!

So I'm going to back up the guys on the other forum. You need diodes there, and I'd go with the numbers recommended (1N4001 has been mentioned in other forums as a viable replacement for that type, which is called an Epoxy Rectifier Diode). 

I'm not perfect, but I do work on electronics for a living (military aircraft) and have worked on plenty of stuff this old. 

 

Also, I'd go ahead and replace all the caps while you are in there. Those are electrolytic caps, and they are usually the first thing to go out on something that age. I'm going to bet that a voltage transient that's usually handled fine by those caps got through and smoked the diodes (which were also degraded). 

 

Actually, I'd just rebuild the whole thing from the ground up if you actually want to use it. This is a dead serious recommendation. You'll get a long life out of it that way. If you were really interested I can talk to you about doing a schematic and etching some replacement boards for people who have these radios. Isn't that hard OR expensive, and it's DIY stuff.
