RE: Design recommendation d needed.

The OEM power transformer has a 2 A. 5 VAC winding, for the 5Y3. Switching to a 5AR4 increases the B+ rail voltage and allows for a larger valued 1st filter capacitor, without increasing the demand on the 5 VAC winding.

Don't go "hog wild" in increasing the amount of capacitance in the 1st filter position.

This Edcor model should be fine for a PP 6V6 guitar amp's O/P "iron".
