Under no circumstances should anyone buy "restoration" parts from Hi-Fi-Audio-Rocks on eBay. He's notorious for send poor or wrong components and providing weak or nonexistent documentation. There's a long thread mover at Audiokarma about this seller.
Is my Dynaco Stereo 400 worth repairing for resale?
After all the years, I’m sure it needs a good cleaning and at least all the cans replaced.
Will I even break even?
