Has anyone altered the Diytube board for
individual tube bias with 4 wirewound pots?
Any good hints on how to proceed?
I have an open frame power transformer. It will
just fit inside the chassis, mounted horizontally.
Will this generate less EMI, than mounted
vertically on top of the chassis?
BTW. I got some NOS GE 12AU7A tubes.
They sound very bassy, but carry an annoying
amount of low frequency distortion. Best to
stick with Tung-sol or RCA 12AU7s.
