Hi Ronson,
It's a shame that the part you ordered didn't fit.
I've attached a picture of the potentiometer in question. It comes from the above-mentioned German company "Audio-Service Schierbecker" in Hamburg (
www.audio-service.com).
The other two pictures come from the T5 Service Manual and show details of the "Wheel Assembly".
Note: After installing the new potentiometer, the internal Test Program should be started and the "037 Pitch Bend Wheel Check" test carried out to ensure that the center position of the wheel is properly recognized and that the correct values are generated (minimum = 0, center = 130, maximum = 255).
If you do not have the T5 Service Manual or if you need details on how to use the internal Test Program, you are welcome to contact me via PN (personal message).
Best regards,
Chris
