On K2, pins 1&2 are shorted. On K4, Pins 1&3 are shorted. Others are OK. - your 0.047 caps are fried in both

The voltages are the same except #4. I must have had the lead on the wrong pin. #4 is 0v. -  better

#1891 is a bulb. There is one wire from the volume pot to the lamp. That wire is 12.2v.  - OK, so it is just 12V to lamp. no effect on the rest of the circuitry.

I've been testing with chassis as ground.

Point 19 is definitely 12v. I must have messed something up before. All points except #4 are the same. - Like I said, it is wrong on many levels, and there are probably short and burns of parts.

X3 and X6 are bad. X2 and X4 are good. X5 I haven't been able to test yet. - It seems this radio had some major surge. Caps shorted, transistors burnt. Or someone tried to plug it into something that it shouldn't been plugged into. I am not sure what those K assemblies are. If they are potted circuits, you will need to somehow replace them. If resistors are good inside, you could try to hook up bad parts (caps) outside.


If you want to be a good sport and keep doing it, great. But it seems like you might have to replace half the parts.
Basically, from what I think might've happened to it, you need to check every single component.

If you do this, we could answer questions one by one as you go along.

PS. To my taste (and had I had that radio in front of me and all the parts available, I probably could fix it in a day or so), to me personally it would not be worth it and I would just toss it. If it has any special significance....sure.
