I am having some problems with the spindle drive speed control on the RX50-AA
drive on my Rainbow.
The drive moter speed sometimes slows down to the point the system gets either
read errors, seek errrors or just won't boot.

After a while the problem goes away for a while, but always returns.

Anyone have any info on the speed control board?
There is not much on the speed controll PWB, with a schematic I think I could
locate the problem.

There is no info on this in the DEC Technical Documentation for the RB100
