I was considering an addon PS board with SS rectifiers in place of the 5AR4 or 5U4GB with a delay timer. As I have already found out, the unloaded voltage of the 5U4GB tube rectified transformer can exceed 560v. This amp already runs at about 505v with the 5AR4 so I am not sure what the voltage would be without the tube loss. Anyone that has SS rectifiers care to shed light on this?
If the SS rectifiers lose much less than the tube what would the effect of a higher supply voltage be on the output tubes and the various intermediate tubes?
Thanks for any help.
