Yes, I realize that the supply was built already.

Dak, its impossible to offer a design suggestion from the picture you have posted.

It may be very easy to get your desired voltages with a switchable FILTER SYSTEM, L1/ C1/ L2/C2 under the chassis, employing two small, high current, less-than-critical inductance chokes, which will also likely be lower in DCR than what you have there, and thus give FAR better dynamics to your Push Pull, higher voltage amp.

So please tell us this:

(1) With a certain Line voltage ( eg 120, 124 ?? )

(1A) what is the VAC at the HV secondary, and
(1B) is it a center tapped secondary.

(2) What is the value in HY , and DCR of L1 and L2.

(3) What is the measured VDC ( B+ ) at C2, and what is the measured VAC at C2, under load.

(3A) What IS the total amp load normally, and
(3B) what is the anticipated mA. load of the P-P amp expected to be.

With the above, we will stop guessing and SEE if we can come up with a great alternative for you, we all would be using PSUD2 and our imaginations.

Fun to do !! Cheers and have fun.
