i have several power transformers intended for use in tube type
power amplifiers, however none of these transformers have a bias tap.
please advise on how to add a proper bias voltage source.
should i just tap off the B+ secondary? should i add a small transformer?
(i have several 48 volt 23 milliamp transformers) please recommend
a method that will provide an adequate and safe bias source? TIA
