It needs between +20vdc and +100vdc, so will pretty much work for any amp since you can simply tap off one of the main PSU +ve rails. There is an onboard voltage regulator. It's just tens of mA of current max.

Default Low voltage fets

Nice circuit ,


But, as a rule of thumb amplifier rail to rail voltage is recommended as a minimum for the used fets .
With the current fets the circuit will operate safe with max power of 56 watt at 8 ohm or double that at 4 ohm loads


Cheers ,


Rens

Yes, thanks for the reminder - we are also looking at some 100v variants of the same MOSFETs.

Well X, you are up to 46 pcb's in less than 24hours, over the next few days as more forum members see this post you should rocket past 100 boards.

Can I ask is the plan to get the boards fabbed and also loaded and tested in China? If so how are you going to handle quality control and make sure genuine parts are used?
