Re: Amp

Try putting new tubes into the amp.  New tubes can work wonders and help to 
"clean" up the amp.  The other thing to check are the capacitors and the 
circuit in general to be sure that nothing is loose, etc.  Values of old caps and 
resistors will drift in time and change the voltages reaching the tubes.  And it 
is important to check the bias voltage for the 6V6 power tube.  Tubes running 
hot will be more distorted than tubes running cooler - this is adjusted by 
bias voltage that is controlled with resistors.
Good luck, and hope this helps a little.
