Bought this used from an estate sale in 2014. Worked great for 3 yrs. Then a
tube short blew a fuse. Replaced both finals and all was well until a few
months ago. The amp worked well for a few transmissions, then the output went
to zero. After a few cycles of this I noticed the grid current which rested
at zero began to migrate negative. As it got worse, the output dropped to
nil.
One suggestion was that one of my new tubes ( from RF parts) is failing.
Another was a possible problem in the AGC circuit.
Other suggestions? Also, I may need a repair tech and don’t want to ship the
amp, so someone in Ohio or driving distance from central OH would be a plus.
Thanks.
