Push Pull tube amp kit from China
#20

I think I found it! I reversed the output transformer ground and feedback and it eliminated the ocsillation and also eliminated the hum and hiss. It "appears" the ground and 8 ohm wires on the output transformer are connected backwards inside the transformer or the plate leads are reversed. So I'll reverse those permanently and do further testing. With the feedback disconnected the gain and distortion are a lot more along with other noise.

If I could find the place called "Somewhere", I could find "Anything" Icon_confused
