You don't even need to go that far. If you're playing it in stereo, press the 
mono button..if audio disappears and you have only surface noise, the disc is a 
vertical cut.

Then take the stereo cartridge out from the arm, and revert the polarity of ONE of the channels; replace cartridge in the arm, and select MONO in the amp, mixing the two channels. Thus, the cartridge will now emit vertical component only.
