Hello,

I just finished my 2nd Skunkie moded Riesong A 10/ A12. It has been so satisfying to tinker and hear the improvements in sound.

On this 2nd one, when I turn it on the amp plays marginally loud, then gets quieter until the maximum volume is just a whisper. The volume knob does affect the volume.

I've swapped tubes, still quiet. re-flowed most of the solder joints. Voltage at B1 is around 300v.

Any thoughts on where to look?

Much appreciated

Tarver
