Right now the amp im working on is running the filament @ 7.5vac and that is really making the preamp tubes hot. Seems using the hammond PT is kind of a pain since these are set at the factory for 115vac on the primary and here in the US we have any where from 120 to 124 vac varing over the US.
I would have used a different trannie but this was a spare so I figured time to use it and be done with it. I won't buy any more hammond PTs so I can avoid the filament over voltage problem in the future.
Which method do you use and prefer? resistor or diode to get your filament voltage down to par?
Thanks for the info
