I'd suspect a RF plate choke which is resonant on 80.  Try a different plate choke.

It is stable, draws full current, but puts out less than the input, I've played around  adding and removing padders to the plate and load caps. There is no tuned input.Any ideas???Thanks, Dick NY1E

Does it load correctly into a dummy load?
