Pre Planning For Modifying A Fender Super Reverb Amp

[TomCarlos]

Helmholtz:

I want to make sure I understand which scenarios we are talking about.

As the AC currents with bridge and two-phase rectification should differ by a factor of 1.414, only one of the formulas/factors for the DC current can be correct assuming the same conduction angle.
I think it should read IDC = 0.88 X Sec. IAC for two-phase cap input. This is #7 as shown in the photo? "Full Wave, Capacitor Input Load"?

This would lead to:

Iac = 1.14*Idc for two-phase
Iac = 1.61*Idc for bridge.

Again, Iac = 1.14*Idc for two-phase refers to #7 and Iac = 1.61*Idc for bridge refers to #6?

Thanks!!

Update: By the way, I am reading "Guitar Amplifiers Electronics, Basic Theory" by Richard Kuehnel. There is a section on Power Supplies Transformers. He covers "some" of what is being discussed here. So I am diving into the details as best I can.

Correct. Both types are actually full wave rectifiers.

And don't forget, with a GZ34 your DC voltage will be 20V to 30V lower than with SS diodes - except at standby.
