Gary:
     Before shipping it off to someone it's probably worthwhile to do a few 
checks yourself.  If Chuck completely restored it, it's unlikely to be a cap 
or resistor.  I would pull the tubes in the audio section and make sure the 
pins are clean when you reinsert them.  Then check all interconnecting 
cables in the same manner, twist and pull them off, check to see if there is 
any corrosion, and put them back on firmly.  Depending on how many hours 
you've played the set since its rebuild, I'd just replace the audio tubes. 
Sending it off to anyone is going to cost some big change.  If you don't 
have a tube tester, even a cheapy available at any hamfest or auction will 
at least give you a go/no go on the tubes.  Also, a squirt of appropriate 
cleaner/lubrication on the switches wouldn't hurt.  Good luck.
