 Pignose bias
--------------------------------------------------------------------------------
 Hello everyone, A friend of mine has a Pignose G40V all tube amp and asked me if the bias can be changed to be adjusted with a pot. Schematic at www.schematicheaven.com .
Can i change R2 a 58k to a 33k and put a 50k bias pot in series? Thanks much for your input. Stan
