SB-104A diagnositic question

[KD2E]

I don't have one, but sounds like you lucked out with an easy problem!!
Not intermittant.
Just sniff the RF back, and find out where its missing.
What is coming out of the driver stage?
What are the DC voltages to the output transistor, OK?
Hopefully you have the manual!
