Turntable not spinning fast enough on 45 Options

[powerstone05]

I have (now) a GemSound BJL-1150. The problem I'm having is that the 45 rotation is quite slow and is noticeable in playing. The 33 seems to be fine though. I checked the belt and it's still in working order. Any ideas?

So you get a strobe disc and measure it. It's not at all difficult or costly. You print this sheet and put it on the turntable and use an OLD STYLE fluorescent light. Rapid start or really old with a starter. This will NOT work with electronic ballast lights. Alternatively one of those neon tester lights would work fine. If the pattern appears to be standing still, it's dead on. These folks also have a 50Hz version if you're not in North America.
