230:22+22Vac 7% regulation transformer will give ~26+26Vac when fed with 254Vac.
That translates to ~+-36Vdc when the amps are off.
If the mains voltage is limited to about 244Vac (230Vac + 6%), then the maximum voltage at the smoothing caps is ~34.8Vdc.

Hello Mike, I'm planning my PSU for a GC with LM3876.
What kind of cap and resistors values do you suggest for your PSU schematics
Thanks
Marco

Hi Ho Hurtz
thanks for the parts list and other updates after all this time!
small pcb's don't always translate to the smallest boxes. hehe
(we) at least I like inside images showing the power supply and wiring interconnects.

Hi infinia!

The project isn't dead, it's just finished ;-)

Sadly I can't provide inside images for now since the amp was build for a friend, and it may be a while until I can visit him.

cheers,
hurtz
