Ameritron 811 problem

[Mudfoot]

Well the amp is working. My buddy put 3 of his NOS tubes in it. Now it's loading up on 80, like it should. I still don't understand, why it wouldn't load up on 80 meters, but all other bands would, though. Tom Rauch told me the tubes were soft. I'm just happy it's working. It's going down the road.

Very very unusual that a set of tubes will work perfectly on all other bands except one. I'd like an explanation for that for educational purposes. Tom W8JI is a busy guy and sometimes does not read full explanations and jumps to conclusions with partial reading. Your initial statement sure makes it sound like tubes could be bad but then with tubes making full power on other bands not. I think you are making a wise choice for sending that amp down the road!
