A quick look at the schematic (a forensically enhanced version kindly provided by the Mighty Mick) to me places cross hairs directly on the zener diode.

So I'm guessing that the zener diode is shorted...idk.

The circuit is open.

At least small steaks...well done...
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.
