VPI Scout - slow speed , help ?

Your orignally 100 notches in 60 seconds is a 3% error, I if read my KAB instructions correctly. That is huge.

How fast is it running?

I am surprised that using the different steps on the pulley have no effect. That is normally how you adjust the speed. I have a Scout with the 300 rpm motor. It is on speed at the top notch, and noticible fast at the bottom notch.

There are differnt pulleys for different platters. Do you know that you have the correct one? I remember looking at a used 300 rpm motor, but it had the wrong pulley. So, I bought a new one with the correct pulley. Just a thought.

Ok, for those of you following this thread: I've just switched out the 300rpm motor for the original 600 rpm model, and the speed is almost perfect! There must be some issue with the capacitor (as someone previously mentioned), or perhaps the pulley, or motor itself.

I'll contact VPI for further diagnoses.

Thanks for all of your suggestions!

At least for now, you are up, and running.

Pretty much all of us, have been drawing straws as to what your issues were, and I guess all we could do is make suggestions. When problems such as these arise, one must hold every component of the drive system suspect. And then methodically check each.

While I'm not sure of this, because I have no experience with the 300rpm motors VPI uses, so I am not sure if the Motor Run Capacitor is typically the same value for either 600rpm, or 300rpm Motor?

Thos are perhaps questions others here can answer, or VPI?

There were a few unknowns about your situation, whether the Table was bought like this, or did you make the 300rpm Motor swap recently yourself, or? I'm getting the impression you may have bought the 300rpm Motor used?

That there was either A., a problem with the Motor itself, and you bought a bad one? Or B, that this Motor requires a different Run Capacitor, which was typically included in the purchase when gotten new from VPIm but you didn;t get included with the purchase? Mark

The 300 rpm motor came with the table; it does have have a different value capacitor than the 600 rpm motor (also included with the table purchase).

I'm hoping VPI can help me from here on out.

Thanks!

I thought I would update this post for future reference. Initially, the pulley was loose on the motor drive-shaft which caused the pulley to slip, resulting in slow platter speed. After tightening the pulley's set-screws, the platter ran fast.

At this point I contacted VPI who suggested I send in the existing 300 RPM pulley, as it was probably for a 12" platter, not the 11 1/2" acrylic, Scout platter.

So, I've just installed the new pulley, sent from VPI, and everything is perfect; solid speed, good sound.

Thanks for your efforts.
