A Beogram 4004 that I had restored in December of 2023 came back to my bench with some significant mechanical damage. After I removed the aluminum panels I found a strongly bent carriage spindle bearing bracket:
Some fairly brutal force must have whacked the deck on its left side to cause the carriage weight to bend the bearing bracket. This basically created so much friction that the carriage was not able to move again. An examination of the enclosure yielded that there is also some damage on the plinth. It seems it was hit by some object on the left side close to the corner where an indentation can be seen:
More scrutiny yielded that the off-switch had a dislocated return spring, which immediately explained why the deck would not shut down anymore:
I did my best to bend the bearing bracket back into shape and I restored the switch:
This essentially allowed the carriage to move again unobstructed and the deck shut properly down again. At this point the deck would still not track properly, however. I realized that the arms were also out of alignment. I restored their orthogonality and parallelism, and then adjusted the tracking feedback. This made the deck work again properly.
I will now play a few records on this deck to make sure I did not miss anything, and then it should be time to send it back to its owner in the UK.
