Hi Folks,
Well, I am finding out more about the ailing 761. If I follow the proper
procedure in the book for setting the driver and final current, ( in SSB
not RTTY) they adjust properly.
Troubleshooting using a scope reveals there is no RF at J8 on the RF unit
board, thus there is nothing at the PA module. I think someone had just
turned the bias wide open so some output would show on a meter to sell it.
It would appear that Q14, the broadband amp on the RF unit is open. I am
awaiting a replacement now. Sure glad I have a dual trace scope..
More later....
