VPI 16.5 Problem


Hi, picked up a used VPI 16.5 here on audiogon--eventually the law of used had to catch up to me, I guess. Worked great for about a dozen albums, but since then the vacuum seems to overpower the turntable--having no knowledge of how the turntable works, it is acting like there was a loose drive belt. So, vacuum really, really works, motor for turntable works, turntable spins (though sometimes starts slowly and then speeds up to normal operating speed), but when both on, turntable stops rotating (motor continues). Any ideas before I take to a repair shop? Thanks very much.

I have 12 beautifully cleaned albums, though.

Kmulkey is right. When I first purchased the 16.5, I came to the same conclusion you did. But pulling off the platter I found that the set screw on the bottom of the platter was loose. I tightened it enough for the flat side of the spindle to fit snug against when re-attached, and it has worked perfectly ever since. Happy listening!
Yep. It's usually because the plastic nut on the spindle has not been tightened or because one forgot to screw it on at all.
Thanks very much, that is encouraging. I tightened the plastic nut as much as I dared, so I will try Bikerduud's suggestion. Is there any trick to taking off the platter? Does it unscrew or just slide off?

Thanks again.
The only thing that I've ever had go afoul in nearly 270,000 cleaning cycles with the HW-16.5 is that the screws that hold the platter shaft to the motor arbor worked loose. If the other suggestions made here for things to check to solve the problem don't work, try checking this.

You would need to tip the machine on its side and remove the bottom panel to do so. If they are loose, be sure to orient the shaft straight and vertical before you tighten them. You may also want to put a drop of Loctite on each screw before you tighten them.

Happy listening.
