Bogen help
I have experience with tube RF amps used in ham radio and am trying to learn my way into audio. I picked up a challenger-100 bogen amp to play with. It operates nice at very low volume, but distorts very easily. I suspect possible bias problems? or bad output tubes, but being 7868's these things are about impossible to find! Anyone have any idea's? or know how to adjust bias on this thing.
Thanks for helping a dummy! Dennis |
