Tandberg 3300X R.to R. motor issue
I was listening to some tape on my Tandberg 3300X, when suddenly, the speed started to get unstable.
Thought it could be the belt.
Opened it and it appeared that the motor was not spinning properly. In fact, it had stopped working at all.
Took the motor apart and cleaned/relubed it. Surprisingly, the inside was quite clean, so I added some fresh oil and tried making it spin by hand. Keeps spinning for about five seconds. The adjustable bottom bearing was loose, so I tightened the screw a little, leaving a very slight play.
Motor back in the chassis: now I can make it start, but only for about 15 seconds, before it stops. Switching it on again gives the same result: 15 seconds, then stop.
Is there anything I have overlooked? Could it be a transformer problem?
My skills with an electric motor are limited to the mechanical side of it, so if anybody could give me a hint and a way to a solution, he/she would be most welcome!
Thanks very much in advance!
