Quote from: saturated on April 09, 2024, 05:20:43 AMThank you sir I am glad I did not have to touch any power tubes...in the back of my mind I had heard about tube biasing and was dreading having to do something like that.  But I looked it up and evidently preamp tubes are just plug and play...?

The two 12ax7 I switched positions were in there really tight.  To avoid broken glass and blood I put on a leather work glove.

I really appreciate everyone's help with this idk what we did but it's sounding really crazy nice it still has a little hum at low volume but I ain't touching it right now.

A little hum at low volume may well be normal for this amp.  It certainly is for others.
Life is what you make it.

FWIW: Unless board mounted and covered up, there is usually an accessible hole in the center of a 9 pin socket. You can use a chop stick or something of the sort to help push the tube out of the socket from the bottom side.
