Pop noise from turntable when power-off the unit.

It's a capacitor issue in the Classic. Apparently, about 10% of the systems with the Classic experience this issue according to Mike from VPI. Some systems just love to pick the pop up upon turning the unit off. Just like the poster above, I simply turn the volume down on my preamp before I switch the motor button off. Mike said pressing the mute button, or changing input will accomplish the same thing with less work.

Are you muting the VAC integrated amp before turning off the turntable? If not, DO SO!!

I ALWAYS mute the preamp while turning off/on the turntable. Put the new record on, clean it, start it and UNMUTE. It's just that easy.

I have a Classic 1 and replaced the cap. It's really easy to do because VPI used wire nuts to terminate it. So you don't need to solder. I don't remember what value cap it was so ask VPI. I picked mine up from Radio Shack. After the cap change the pop was still there but very quiet and no longer a problem.

VPI has known about this problem for some time. I am surprised they have not just started using the higher value cap on their motors yet. It's such a simple and inexpensive fix.
