Hi
I have a couple of questions regarding PT secondary ratings. Is there any reason not to use a 40V transformer for a +48V power? After the bridge it is going to be ~56VDC so plenty of a margin left for regulator to regulate. Same question for heater PT ratings, 7VAC should be enough (~10VDC after the bridge)
and again ~3V margin left for the regulator to do its job?
Thank you
