help with my sony ps5550 please...

[boogel]

hi guys, suddenly my ps5550 lost speed and control (either 45 or 33...), what can probably go wrong? i've checked the belt and it's still ok... any inputs is very much appreciated, TIA!

the most common problen with TT speed control is oxidized potentiometer(s). Please elaborate on the symptoms (erratic, too fast, too slow?)......Any good (like Caigs) deox/lubricant will probably get things right!:D Chuck

thanks chuck! the speed is too slow, the speed selector doesn't work, the pitch controls either. i tried contact cleaner on the pitch control potentiometers but it doesn't solve the problem. what i'm puzzled about is the selector switch for the 45/33 speed isn't working! anyone experienced that kind of problem? thanks! manny

The service manual has a fairly straight forward explanation of your TT's speed control (increase/ decrease voltage to DC motor). Study it some and we'll go from there. :) Chuck
