Rick,

Before we beat the subject to death, I'll give you one more piece of 
unsolicited advice:

If you ever need to remove the cover of your amp, remember that there are 
lethal voltages present inside.  Even with it  unplugged, turned off and 
sitting in your front yard, it can still kill you.  Parts like bleeder 
resistors can be bad after so  many years, or perhaps it wasn't  assembeled 
100% correct in the first place.

This isn't high voltage like getting zapped by a spark plug wire while 
working on your father's Buick.  This is smoke out of your ears, hair on 
fire, D.O.A. high voltage.

have fun, but be careful.
