Please review this power supply, and let me know if it is OK. It is meant to power 4 gainclones for Bi-amping, and a preamp. The preamp will have filters and regulators on-board, and the gainclones will obviously have their caps on-board.

It is very nice, but for the power amps, isn't there a big problem with hum, if you connect 1 amp, no problem, but with 2 amp's you create a large ground loop ( becouse you connect the 2 bridges togetter at different places ) , and the more you connenct the bigger it gets.

I could be wrong on this one, but still i think it will be a problem, maybe seperated bridges for every power amp could solve this.

I think if you do it like Paul intended to (so no caps in the PS)
every amplifier has got it´s own star ground between the caps in its own enclosure.
Actually I have to admit I haven´t got through the hole "This is not just another gainlone"-thread. There might be an answer to this.

Jens - in need of a flatrate to go through all those long threads😉
