Proton Amp and Pre-Amps - Mods

I was wondering if anyone knows someone good at modding amps and pre-amps, and if Proton would be a worth-while venture?

I scored some equipment with mint condition chassis for a very nice deal, and with a little work I think I could get some very reasonable sound for the money.

Anyone want to share experiences? DIYers?
They are no good at all.Dont waste time or money.Sell them to me instead,thanks,Bob
Proton has made some very decent mid-fi pieces. I've owned their electronics and speakers. Oft times I've liked their pieces better than competing NAD. As far as modding them.....not. Enjoy them for what they are if they clean up well and operate properly.
Does anyone here have a phone number for Proton in the USA?
