Great Info - -I have a question

Post by ChuckLogan » Wed Aug 09, 2006 12:40 pm

I am building a JTM50 which is tube rectified. If I want the B+ voltage to
be 385 what factor would I use to allow for the tube vs diode rectifier?

ie what multiplier can be used for Tube rectified amps . . I am aware that the voltage can vary by using different classes of tube recs

Cheers

What are you looking for in general? A gain monster?
So is it the more Henries it has the cleaner it gets?
