with all original stuff that came with a new device. It looks like it has not been used (much).
It wouldn’t play properly, of course, so I installed a new belt from a collection that I know works. Unfortunately, it still has the same problem.
I have manually checked the working of the tape transport and it works good. Camwheel works ok for the 3 modes etc.
Here is a video of the problem:
I am kind of stuck right now. Does anyone know what I could try next?
I’m quite sure the belt is ok. It is from a batch I use all the time for these players and they all perform beautiful with it. It surely is not too tight.
I have actually already cleaned the optical sensors, it did not fix it.
I have an 170 that needed a new belt, so I had it open anyway.
I took the motor and installed it into the 134.
Unfortunately, no success. It still reverses after a few seconds like in the video.
Oh, and FYI:
The 170 motor installed causes the 134 to not show direction anymore in the display, i.e. it keeps saying ‘side A’.
Weird. As if this motor has different interface somehow on the pins. It does spin however.
