Hi friends! I'm brand new to this site, but have been perusing it for several weeks. I'm an old-school guy, luthier and professional musician. I've decided to go with a vintage tube receiver, preferably a Fisher 500C. I need a little guidance as to where is the best place to pick one up. I see several "garage finds" on eBay, and some supposedly well restored versions...but local pickup only! Any suggestions as to where to locate a good solid example, and who's the best restoration person for these units? Thanks!
