    Thanks for the help folks...One of my amps is a rewired Traynor Bassmaster...it
    had a master added among some other stuff..problem is, the way I prefer to run
    it is with the master wide open, channel vol (gain) on around 9:00...volume and
    od controlled by guitar volume...now lately, when it is like this, it has
    become very noisey...even without the guitar plugged in, as you raise the
    channel volume, it sounds like feedback from a single coil...it gets more
    intense as you raise the channel volume... if I tap on the tubes/chasis/case,
    it
    is all very microphonic..all the same sound and volume...if I reverse the setup
    (master down/ channel volume up) most of the assorted noise goes away,
    including the microphonics.........would this indicate a bad El34? or maybe
    both are bad?..or a cracked socket?....I say this because the more you stress
    the power tubes the
    worse the noise problem is...any help/opinions would be greatly appreciated.I
    prefer to order my tubes and dont want to order till I have an idea if this is
    the problem or if it is related to an internal problem or something.... Thanks
    again....JMsDvd

    The noise comes from opening the master all the way and then controlling
    volume with the gain. If you want to run it this way you should get rid of
    the master volume (or get a non-master volume amp). Otherwise, you're going
    to get noise because that's just what happens when you turn the volume all
    the way up, you get hiss and noise.
