What to do with inherited vintage Revox gear.

"I hate to part with them but......"

Then pay for a real sales ad.

Is that "constructive" enough for you?

Oh someone didn't get enough hugs when he was little. 

Put up an ad and sell them if you don't have access to a qualified tech.

Might want to go on tapeheads.net and see if anyone there can help you out.

Also, I am not in anyway affiliated  with this outfit nor have I used them, but according to its website they are in Surrey BC and appear to do repair work including reel to reel so might want to discuss with them
