|Tom L||V-4 Bias mod|
Sometime back in July, Graywater wrote:
On closer inspection, I see that my amp does have the V-4B type of bias circuit (even though it's a V-4, not a V-4B--I should have noticed this before I did the mod!). So I need to take out the trimmer I put in at R49 and put one in at R60 like you did.
So, what values did you finally come up with for your mod? And did you wire the trimmer as a pot or a rheostat?
Thanks for being patient with me while I learn.
