Does anyone have the service manual for the Numark TTXUSB?
I want to repair the motor of this turntable. When being cold it stops turning and sometimes even turns backwards, which gets better after you turned it with your hand a bit. So this sounds like capacitors having got old. Then I could also replace the the 2SB1340 and 2SD1889 transistors. Someone already did some soldering on the motor and added a foil capacitor to stabilize the motors Vin I guess, although its power supply provides a stable voltage. Would like to know what is still original here. Does anyone have experience with this turntable?
Cette question est-elle utile ?

Hello coldspark, i am Eduardo From Brasil and i can help you .
if some 2sb/2sd transistor was problem you need to change the smd mosfet drivers too. its 7002 transistor. BTW, if possivel, can you tell me the value of r55 ?
