Turntable speed slow with quartz lock

I have an 30 year old Harman Kardon T-60 turntable that runs slow (according to strobe) while in quartz lock mode. I would chalk it up to a bad unit except my friend's unit does exactly the same thing. The coincidence is too great for me to ignore. Any ideas on how 2 units that use a quartz referenced oscillator could both run slow. I have recapped the power supply on mine with no effect.

Dear Heyraz: Here on page 6 of the TT service manual you can read about: http://www.vinylengine.com/library/harman-kardon/t60.shtml

If that does not help you then maybe the oscillator is out of specs.
Now, you can run that TT with out the quartz mechanism ( off position. ), do you already try it? runs with out speed deviations after you set manually the speed?

Regards and enjoy the music,
Raul.
