Bingo, you are correct. Good eye there HiDef. That is exacly what is wrong with the amp. The pic took with the tubes lit up is from another viking. should had mentioned that but wanted folks to see what it looked like when power was on.  Both supplies are down at the moment. I will get them fixed by the week end.


Wait till you see the inside pictures. Almost better than the outside.

The owner of the box I got it from was told he could swap tubes by a guy that did not know what he was talking about. He had plenty of 3-500 at the time so he sold the original tubes. Mis informed I would say.
