RE: a filter or a crystal oscillator to reset the freq is more important on a turntable

"The third thing to use is a variac to reduce the voltage into the turntable as that will also reduce noise dramatically. 65-70v works great on an LP12."

Bingo. I've had my table plugged into a pretty decent line conditioner with good results for many years but one of the bigger bang for buck tweaks I've experienced is running my AC Gyrodec off a variac after Harry Weisfeld from VPI suggested it here in a thread a year or two ago.

For $50 it is a no brainer on tables with an AC synchronous motor. Both the VPI SDS and Linn Lingo power supplies drop the voltage after startup to around 70 volts. With a variac you are going to have to do it manually so there will be an extra step involved in playing a record. Then again, a variable output transformer is $50 vs maybe 20X that for something like the SDS and Lingo, which clearly do a few other things and offer up 33/45 speed control as well.

I run my Gyro at 68 volts.
