I can't speak for the FM-3 mods he sells, but you can do far better with the PAS than what he's offering.

The capacitance for the fillament supply should be increased far beyond what those small caps can offer. I replaced the selenium rectifier with diodes and increased the capacitance by about seven times the stock amount. It took the sound of the (otherwise) stock PAS beyond my Audio Research SP-3-A-1.

I'd look elsewhere for PAS upgrades. Email me if you have any questions (and no, I'm not selling anything).
