[TenTec] Triton 4 SSB board

[admin]

HI all,

Been working on another Triton 4 and have it working fine on CW.

But have problem SSB generator board, replaced to the Microphone amp chip,
but still has low mike gain. Check other TT540 and with 30 mv of audio in get 100 watts indicated on the Bird 43 into a dummy load. Injected audio into the problem board it takes about 1.8 volts of audio to get 100 watts output.

Everything reads right with voltage and resistance measurements. Suspect 
the the CA-3053 is the problem stage, looked it up on ebay , it  has
also has a better replacement listed as CA-3028 ?, any one have this 
problem?
Thank you for the read
