Dead Pignose G40V Tube guitar amp Bad power transformer How to Mod for Harp playing 6V6 plus bias



Published
First one in the shop. Arrived DOA. Most expensive failure, Yep, the power transformer. Lucky, I had a NOS Stancor replacement. The owner told me in the past, the amp was to loud for recording use with his harmonica, and wanted it more user friendly. In this video you will see the tranny install plus modification for 6V6 use. Adding variable negative bias to this amp is a breeze. Even though it was a China built machine, it really sounds great!
