If you can make it up I85 North to 985, take the Gainesville exit to HWY 129/Cleveland HWY North. Jack's Electronics and TV Repair. He is an old man who has serviced many a walnut enclosed Pioneer Receiver. He does reel to reel, tubes, studio mixers, tv's, ect. he cleans them up good, and gets rid of dust and tarnish. $35.00 bench fee. I like to order all the parts myself online, then take them all to him for service.
Hope it's cool if I can plug him.
Look him up.
