[TenTec] Troubleshooting Tentec 422

[Bry Carling]

I am still working on my Tentec Centurion 422 amplifier that failed.
No outpu. 
Tank circuit not tuning.  The best I can deterine using a GDO there is a resonance only at 22.5 MHz regardless of where I set the tuning caps or bandswitch. I tried jumpering across the bandswitch and nothing changes.
I
 used both a GDO and also used an antenna analyzer coupled diretly to th
 eoutput point, with everything else an and out of the PI network 
disconnected.

Any other clues?
