Please Help. J. A. Michell Gyro SE - Speed Issue

Humm, something odd going on at fidelity imports.  No reply from multiple emails.  Not sure what's going on 😔.

Sorry to hear that Quincy. It might be time for a new turntable or you might try contacting Michell in England. 

I wouldn’t give up on fixing this turntable. I’m not familiar with your motor or power supply, however, the problem could be with either. I upgraded to the HR Power Supply which has the speed adjustment on the back.

You can contact Michell here, they will likely be able to provide some guidance:

I would call in person rather than email. They look a little swamped.

Interesting

"I literally turned the screw CCW at least 6-7 full turns.(what could go wrong??) The table did slow down to a snail pace faster that 33.33. I use a Cardas Frequency Sweep record that has a strobe on one side. I place the needle on one of the frequency sweeps and then hit it with a strobe light. So, at least, for today, it is again working,"

I believe that turning the speed control screw wiped the contact clean ,  try doing this in both directions 10 times and then check/adjust with the Cardas timing label .

I am curious about the Mobil oil , is that recommended ? I use a lightweight oil without any detergents as recommended and purchased from GEMS maker of George Merrill Turntables .

I noticed a similar issue with my Gyrodec, which I have since 2000. I recently installed the new springs, did an oil change, and changed the belt as well. The table is running just slightly fast. 

I have thought about replacing the original power supply with the HR but I would need to also replace the cable lead from the motor. Years ago the connectors fell apart so I had them just soldered together. I had an email exchange with Fidelity Imports about this but have not heard anything back from them about the cable.
