Hi Eric
Thanks for your response. Greatly appreciated.
I reckon its safer to run the amps with the prescribed 22V rails. On reflection, my speakers are a nominal 4 ohms, so definitely better to go for higher current.

PS: do you see any issue with using the IRF 140 Fets, instead of the 240 as is commonly used?

Kind Regards
George.

I don't have any personal experience with the IRF140 devices. I know others have used 044, 240, and 244 with good results...

I've used IRF140 in every aleph I've done. Just keep in mind it's a 100V device.

Bonus: you need less of them.
