Hi all, thanks for your threads.
I recently cleaned my TT,and inadvertently had the belt twisted w/o knowing it. Something immediately didnt sound right so i checked VTF and platter speed. They were the same as before cleaning. Then i realized the belt was twisted, and correcting that at once normalized the sound. The belt on my TW acustic TT goes round three motor pulleys. Even with a twisted belt, the speed was dead on with a strobe disc. Didnt even waver. I assume a twisted belt is bad for speed stability and in this case caused the problem at hand. So perhaps the strobe disc is not sensitive enough to pick up the speed "jitter" or it was something else caused by the twisted belt that degraded the sound.
Happy New Year.
