kevin Hamilton	While you're on the subject of Boogie bias....... I have a Tremoverb combo. It can use silicon diodes or rectifier tubes and also has a hi-low power switch. Here's the problem. I have tubes that are set to run at the correct bias when running at high power and silicon diodes. As I change to half power or tube rectification the plate voltage goes down and as a result so does the bias. I guess the solution is an adjustable bias pot. Has anyone added an adjustable bias to a Tremoverb and if so, whats variable resistor value should be used? Thanks, Kevin
