OK!
10 years ago I ripped apart an old Yamaha record player and completely rebuilt it!
It was very fun! ... but it ended up going 5% to slow, I never could figure out why..
But it had thunderous bass!!! Really crazy!
I primed the underside of the alu platter with noxudol, a car chassis dampening compound!
It was as dead as a doornail, did not ring!
