Carol, make sure that it's not the choke and not the trans.

Hello all....
This past weekend I ran into a new problem in the CQWW-RTTY contest.
For some reason, the power transformer in my Alpha 76PA started
buzzing big time everytime it was keyed.. The transformer is solidly
in the amp so that's not a problem. Early on, I asked a friend of mine
in DL land if my signal was clean and he responded YES !!! Then
Saturday evening I received a report that my signal had a buzz on it.
Same problem on CW. I could understand a bad tone if the electrolytics
were bad, but I am not sure. HV is good, no major drop when amp is
keyed, and everything tunes up as usual. Anyone have an idea where to
start troubleshooing the amp? Has anyone else had this problem?
Carol
