with the full voltage of SS rectifiers. I would not think of doing this on a whim and not have sufficient voltage capability with my capacitors. Having a slow voltage ramp up is not only a cathode stripping issue or non issue in audio amps, but a parts and tubes issue as well. Off to full on voltage cycles will wear out your parts and tubes much faster than a controlled voltage ramp up via an indirectly heated rectifier.
With my dual tube rectifier power supply it is an opportunity to easily explore the possibility of having a higher B+ voltage for using other tubes and getting more flexibility out of the power supply. I don't see any other way of doing this on the secondary side of the PT.
FL, pointed to a method involving a switch on the SS rectifiers which is certainly doable, but i am hoping for a plug in solution. cheers, Dak
