Finally got this radio back on the bench.
I believe you're right on the green/white wires on the foil side, disconnected I have no speaker, so they likely ran these foil side due to the damage in the power area.
The receive is still poor, but both this radio and my tuned/aligned General Lee were on CH4 and TX/RX back and forth. Last time I had this radio on the bench it was receiving 1ch low, but wasn't this time. I wonder if the RX drifts when it warms up?
I've thoroughly inspected the foil side, cleaned up what I could, confirmed no shorts, no more bad solder joints. At this point I think I'm just going to be chasing and replacing old/bad components, probably a lot of bad caps on this old rig.
I think I have all the electrolytic caps in stock, but I haven't yet put in an order for disc caps. I'm going to try to identify them visually, compare against the schematic of the 14b board, then see what I can find on digikey.
According to the Bird43, on RF output low I'm dead keying 2w and swinging 4w, and on high I'm dead keying 3w and swinging 5w. I think the aftermarket peak kit I put in the Bird is lying to me so I'll check on an MFJ cross-needle to see what it says, but this could also be a result of old components or that oxidation/corrosion on some of the trim pots.
Is it possible to wire the un-used 10khz wire to the CB/PA switch, so I can have switchable +10khz?
Edit: The only frequency counter I have at the moment is a cheap chinese one w/ bnc connector from ebay that would surprise me if it were accurate at all. I need to get an RF sampler bought or made before I can use it, though.
