How often do you replace your belt?


No, this is not one of those questions where I'm looking for an answer like, "After Thanksgiving." The belt on my table is over three years old. When I place the brush on the vinyl, it slows down now. I'm also questioning the sound quality lately, I'm thinking, the belt may need replacement. Does anyone have a formula? Like every year or so? In which case I'm long overdue? I just ordered a new Turbo power supply. Maybe all I needed to do was replace the belt? Hmmm...

Thanx,

Dave

My Oracle dealer, about 25 years ago, told me about the twist in the belt tweak. I used it on my Thorens back then, and use it on my Oracle today. I should have my new belt in a day or two, and my new power supply sometime after that.
I'll post the difference with a new belt after I try it out.

Rubber renew. Google for the best deal/local sales. $5-6 for a small bottle which will last forever if you're just cleaning turntable belts.. your belt will be just like new again... maybe even a bit better. Talcum powder sounds like a bad idea, odd VPI would suggest making the rubber surface less likely to grip the platter at 100%.
I think, for $10. I may just order a new one as suggested...
I'll let everyone knwo how it goes. Then again, while waiting for the new one, I may try some cleaning magic.

Thanks,
Dave

I did it once on my Transrotor TT - in 25 years!
Generally speaking belts are inexpensive, if you have reason to believe that yours needs to be replaced, get one and then tell us if you really needed it! I just buy a new TT when the belt gets worn! : )
