Quote from: joecool85 on April 11, 2024, 03:53:39 PMI recommend making sure that the input jack is clean and connected well to both line and ground. If not, it could be only letting some signal through causing these issues.I will, thanks.
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.

I am unsure if sharing a ground with an external amp and an internal amp would cause any issues?It can cause issues with ground loops or worse. Some amps require their output (-) terminal to be isolated from ground for things like current feedback schemes.
If you want it to be safe as possible, use a Cliff S2 style jack, which will be insulated from chassis, and also will allow switching of both the positive and negative wires.
