Pioneer SA9100 & TX9100 repair near McLean VA? (Worth it?)

Hi, my neighbor's husband recently passed away and left her with a number of interesting pieces of vintage gear. Included are the following: Pioneer SA-9100 amp (a beauty) and Pioneer TX-9100. I smoke tested both, but stopped because the amp failed to output anything other than background noise and an exceedingly weak signal to my sacrificial speakers (known to be good).

I'd like to get an estimate for repair of both (also looking at re-capping/mods), preferably local to avoid shipping. In my opinion, both of these have a very nice look and feel, and some great features. I just don;t know what they sound like "fixed" or "modded".

Do you think these are worthwhile repairing? 

Do you have a suggestion for a repair person who is familiar with these?

Thanks!
