Hi there
We have recently purchased a second-hand Ameritron AL-811X amplifier. It
works fine on all bands except 10/12m where it is difficult to output more
than 300W without turning the anode parasitic resistors into smoke!
I have tried replacing the original carbon composition resistors with carbon
film types but the problem persists. It looks like this is a design flaw.
Has anyone else encountered this problem? If so did you find a solution? Any
advice would be appreciated.
Thanks & 73
