33 speed problem on a Technics SL-QL1

mattjk · 1st January 2005, 08:52 PM

I have an old Technics SL-QL1 direct drive turntable. The 33 speed is a bit slow. The pitch light moves counter-clockwise at a steady pace... about 2 - 3 bars a second. In 45 speed, it is rock solid.

Is this something that I can repair myself without a frequency counter?

I have done some searching around the net, and found that the powersupply caps may be bad. I have checked and none of them or bulging or leaking.

Please let me know if you can help.

Thank you for your time,
Matt

Do you have a service manual? This might help, not sure. I just got one off of ebay yesterday for my Technics SL-220.

Many Technics turntables have speed presets inside.
Don't know about this one though.
