In drawing up the B+/B2+ supply, I am faced with the need to supply much less votage to the 6922 than to the 6Y6GTs. This could be done by either (1) using dropping resistors after a split "check valve" like El Cheapo, except with much larger resistors (about 6KOhm) or (2) doing a second supply, taking power off the N-77U but not using the booster transformer that the B+ supply uses.
Is there a preference in which way this is done? Using larger resitors seems wasteful of power, but a second bridge and filters seems like overkill. That said, we will need a screen supply anyway, so it could go either way.
Thanks for any thoughts,
Jeff
