I would have never predicted this. But, I am STILL using my 1972 Sansui 7000 Receiver I got from the Navy PX in the Philippines.. About 10 years ago, I had to go through all the switch contacts, clean and lube them. Other than that, it still works great and drives all the speakers throughout my house and garage.
I had to retire my 1972 Gerrard Zero 100, as the turntable rumble from the hardened rubber drive wheel got annoying and unsuitable for recording transfer. I found a Yamaha P350 Belt drive turntable to use, instead. I think I paid $20 for it. Just needed a new belt. I don't really use the Sony TC-650 Reel to reel much anymore. But, I still have about 400 Vinyl record albums. Most of these were played once or twice to get them onto tape. Now, I am slowly transferring these to CD or MP3.
Cheers,
