bias pot
another question regarding my 5f6a build. im getting ready to place an order for a multi tap OT and I was thinking what else do I need? would like to make the amp capable of adjustable bias and im not sure of what value/type of pot I should get or if I need a resistor or two. I didn't research first this time. thanks again in advance.

Re: bias pot
well I see the 50k bias trimmer in one post and immediately after it says nobody should be building an amp with 450v plus if they have to ask these type of questions so which one is for me lol?

Re: bias pot
