|5F1 Strange sounds||I have just finished building a 5F1...|
I have just finished building a 5F1 and I am getting a strange sound when the vloume is set between 11 and 12. At peak volumes there is a buzzing oscillation -- but only when I play through the amp -- not when it is idle. I have swapped the preamp tube-- but no help. Does anybody have any ideas?

What output transformer are you using?
