VR 3 ad J28 will only have power when CB./PA is in CB mode, you're TXing (INTO A DUMMY LOAD! CAREFUL!) in ANY AM SSB mode
Wonder if you have a bad trace on the front panel board that killed your TX and Pin 2 - these two are the upper two pins of the mike socket - No audio (Pin 2) and No TX (Pin 3)
Does Audio go quiet when you key the mike? (I think you said it did - but making sure...)
Because - D25 is the TX power diode for the SSB (not thru clarifier) D24 is the RX SSB clarifier - goes thru front panel....
So when you TX - D25 goes ACTIVE - POWER ON BOTH SIDES.
When in RX, you will have power on D25's THE BANDED end - but not on the other (Polarity - why it's a steering diode)
In RX D24 is what D25 was..
So, when in RX - D24 SHOWS POWER ON BOTH SIDES IN RX Mode ...
When you TX - D24 shows power only on BANDED Side.
We'll keep it simple for now...see if the above can help us sort it out...
