Ok Chaps, after ruling out sticky shed syndrome, the problem seems to lie with either:
1. The pinch roller
2. the drive belt
3. the motor.
Here is the pinch roller.
I have a link to buy a new roller, but its in Japan, and it may not be the cause of my problem.
Ok...the front of the machine.
In this pic, I have drawn on where the drive belt runs, behind the facia.
If you press play, the motor runs the untoothed belt, and turns the pulley with the capstan on it. the pinch roller closes on to it, which should pull the tape through, and it does, but on playback, there are massive speed and therefore pitch fluctuations.
If I hold the capstan or the motor pully, the motor slows down and struggles to speed up again. if you give the capstan a quick twist, it will speed up again. If you hold the roller so that you stop it from turning, it will not start again, until you give it a twist.
To me, in my admittedly unexperienced opinion, this seem like a weak motor.
if the motor was strong, surely, if i held the capstan, it would make the drive belt slip.
heres the motor from behind.
I reckon its the motor.
Anyone else have an opinion?
Are these motors still available?
Thanks in advance.
Phil.
