CRC Power Supply (Class A amplifier)

Is it possible to use a center tapped transformer to power this? I have two old Stancors and hope to use one for each channel, but there are not two separate windings. The transformers are very large and would provide far more current than necessary.

Thank you Prasi,
Is it possible to connect the upper leg of AC1 and the upper leg of AC2 to one tap,
and the lower leg of AC1 and the lower leg of AC2 to a second tap? This old Stancor has the same winding configuration as a Thordarson 23V434 https://4donline.ihs.com/images/Vip...-17.pdf?hkey=EF798316E3902B6ED9A73243A3159BB0
if I bridge taps 9 & 10, 8 and 11 give me 19 volts, which is what I want.
This is my first attempt at a class A power amp power supply, so all help is very much appreciated!
Mark

Yes, I received a notification also to ask 2 cards to Prasi and I did not see any post. I do not have the message but the request is PauloPT it seems to you and if it is not a mistake it would be nice to confirm the request to Prasi.

@Prasi:
I will see to edit the first message and mention the availability of boards.
