should I or should I not

[rocknroll1]

I have been looking for a pioneer PL 550 or 570 for a while. The 550's seem to be few and far and the 570 are all over 1K. I found a 570 in better than average shape except the tonearm motor for the automatic features does not work but still operates fine as a manual. Other than that it is in better than average shape. i don't mind it being manual but will this cause other problems later. also what other model motors would work if I choose to repair it?

Using it as a manual turn table should not cause any problems later on.

There have been attempts to organize group purchase for the tone arm timing motor in the past......( do a forum search)

As Balifly said, there was an attempt to organize a group buy. I was the first to attempt it and others also tried over the years. I couldn't get enough people to commit. It required at least ten to make it work, since the motors had to be ordered directly from the manufacturer in Japan.

I sent a motor I had to the west coast rep for Nippon Pulse motors so that they could source one from their existing line. They do still make a motor that is exactly like the original except for the rpm's; however the speed isn't that critical. Anything from 3 to 6 rpm would work. The speed of the arm travel is not that critical, unless it is too fast. The original speed is approximately 6 rpm, which I determined by removing the motor and plugging in into a wall outlet and counting revs for one minute.

I also bought several different synchronous motors online trying to find a suitable replacement, but none of them worked well enough.

The usual problem with the original gear motor is a plastic gear on the shaft that gets brittle and cracks after nearly 40 years. Some people have successfully repaired the gear or had one custom made to fix the problem.

Of course manual operation can work fine too. The one advantage of the 570, if limited to manual only. vs the 550 is the slightly longer arm of the 570.
