Power Supply Help

[Cambe]

Hello Everyone,
I need some help with the power supply for a amplifier I'm building.The amplifier is class A/B.I have a 320VA transformer with
4 X 11V secondaries ( 8 - wires ),no center tap from Victoria Magnetics.I want to power a stereo amp.The amplifier can use 12
~ 80V rails. Thanks in advance.
Sincerely
Cambe

one option is to make two sets of two windings in series .
you end up with 2 * 22V (one for each channel).
giving a regulated voltage of about 28 volts.

experiment with connection various wires until you have two series.

I am a newbie at this. Can you be more specific?How is the grounding handled?
Sincerely,
