i've had similar problems with my direct-drive JVC table (JL-A40). a table
geek at the local vintage electronics shop recommended i flip the table
over, pull off the bottom panel, and re-lube the drive gears (to which you
should have easy access after removing the panel). it actually worked--it
stays on pitch MOST of the time now and hardly fluctuates at all.
make sure you use some type of plastic-safe GREASE, though. NO WD-40! i
used Vaseline, believe it or not. ;)
HOWEVER, if that doesn't fix it, there's possibly a more serious problem
with the drive assembly. i'd take it to a repair shop if that's the case.
