Hi all. I hooked up my Linn Sondek LP12 for the first time tonight and
within a few seconds, to my horror, I noticed that it was spinning
records too slow. I'm in the US, but the LP12 I own (which I purchased
used) is marked as a 110V one, and the sticker on the back says that it
should be able to handle 50-60Hz.

It has the Valhalla power supply and the Cirkus motor upgrade.
Visually, everything appears to be in perfect condition, and I couldn't
tell that it was spinning too slowly until I put an LP on. It's like
it's playing a 33 at 28rpm (by my estimate).

Needless to say, I'm hoping that there's something simple I've
overlooked. I do realize that the LP12 is finicky... . Hopefully
someone here has encountered this problem before.
