On K2, pins 1&2 are shorted. On K4, Pins 1&3 are shorted. Others are OK.
The voltages are the same except #4. I must have had the lead on the wrong pin. #4 is 0v.
#1891 is a bulb. There is one wire from the volume pot to the lamp. That wire is 12.2v.
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.
X3 and X6 are bad. X2 and X4 are good. X5 I haven't been able to test yet.

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.

Thank you. I have to take a break from it for about a week. I'll have to do some thinking. I was toying with the idea of making a PCB and populating it with available parts. Just not sure how I would connect the tuning circuit. I could remake the potted circuits, but I'm not sure I feel like it. I was thinking about maybe just trying to connect some good caps on the outside. Like I said, I'll have to decide. Parts are very hard to find. If I had all of the parts, I wouldn't hesitate to rebuild the whole thing, but that's not the case. Thanks for all the help. I'll let you know.

Alrighty. I'm back. I'm not ready to give up. Suggestions on where to start?

See above.

Try to see about the shorted caps etc, remove the transistors, and do not populate them until you rectify the sub-assemblies situation. Make sure all caps are good, diodes etc. Resistors, of course.
Then you can proceed with the transistors, one-by-one, from the RF X1-X3(see if you could get the voltages more or less within the reasonable distance from those listed), and then to the audio and the audio-power ones, X4-X5, and only then X6.

Do not plug-unplug the speaker while hot. And when working with the X6 in-circuit, it is better if the speaker IS plugged in.
