Adjusting tt speed on the cheap:any tricks?

Hi
I have a Michell table with HR power supply which has speed adjusting screw on its back.I don't want to spend $100-150 to buy a strobe disc with a strobe light so i'm trying to adjust speed on the cheap.I did some adjusting using a camcorder with a built in stop watch and counted if the table did 33 1/2 turns in a minute.Any other ways to save a buck?Thanks in advance.

you can get a free strobe disc here:

No Stobe light is needed, simply use it under a normal incandescant lamp (60hz - use the corresponding disc)

If you want something a little more 'scientific' get the Cardas LP which is great for set up and break-in and also has a device for setting speed with a regular lightbulb. You should have this LP anyway, the speed control is just a bonus.

The stop watch works well, but average it over 3 to 5 minutes for better accuracy.

Do you have any albums on CD and LP ? If so play them and adjust until the pitch is the same. The ear is quite good at detecting pitch differences so this will get you very close.

Many strobe discs are marked to work with lighting that pulses 120 times a second, just like regular wall power. Maybe you could xerox a friend's strobe disc then use a regular incandescent bulb light in a darkened room.
