I had a similar problem and replaced the finals. It didn't make a heck of
a lot of difference. I eventually traced the problem to a shorted pin
diode in the receive bandpass filter switching. This short messed up the
logic and the 20 meter transmit filter was in the circuit all the time.
The only bands it would work properly on were the ones above 20 meters.
Try it on 10 meters and if that works, work your way down through the
bands until you find the highest one that doesn't work, then check the
receive pin diodes for that band. If it's the same problem I had that will
bring it to light and save the expense of new finals. I think the ones I
removed from mine were probably OK but I'm not going to risk the
posibiliity of damageing the board by resolder just to prove it.
