[QUOTE="Skylar, post: 1101068, member: 17146"] Apart from the inductor, you've described a [i][b]Universal PSU[/b][/i] which is recommended to be used in FirstWatt amps. [url=https://diyaudiostore.com/products/universal-psu]https://diyaudiostore.com/products/universal-psu[/url] I had the PCB's for the Universal PSU, but didn't use it because my M2 is already very quiet - probably because there are two CapMx's which provides ample ripple filtering, judging by how quiet the amp is. Anyway, this is DIY after all and I'll keep on making changes, even if it's just to experiment. Btw, the BOM of the Universal PSU specifies snubbers of 100nF and 1R. [/QUOTE]
