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

Thank you all for the excellent replies'.

I should add that I installed a new belt a few months ago.  I put a new belt on every 4-5 years.

I change the oil every winter.  5W30 Mobil One.

Yes, I have speed control in a black box that sits below the table on another shelf.  There is a small screw (horizontal) to turn that adjusts faster or slower the speed of the table.  The table is running so fast there is not enough adjustment in the screw to slow it down.  I don't know if its a DC or AC motor, does the speed control in the box provide a clue?

I will attempt to contact fidelity imports....thanks for the tip.

And thanks Bill for the Pots cleaning tip....I have a can of electronic cleaner, I may try that as well....

@quincy Can you confirm that the belt is in the top position of the motor spindle? And not the bottom position? That’s the difference between 33.3 and 45 rpm. 

Hi rhg3, yes the belt is on the proper upper pulley. Good call, that slip up would cause the issue for sure! No, its not playing at 45 rpm...someplace in between. I did contact fidelity imports. They are kind of busy with the show over in Europe, and seem to be short staffed. I’m trying to be patient.  According to the electronic link provided from above, I have a DC motor....no knurled nut just below the pulley...

I always use a record clamp. The belt is new, early spring of 2024. Platter oil changed Xmas of 2023. Proper pulley location. I was putzing around again with the speed adjustment screw in the off board black box (today). 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, somewhat, but still concerns me as to why it went haywire in the first place.....I do appreciate all the feedback and help as I seem to be clueless as to why this is occuring.

This table was purchased used from Audiogon in 2003. Actual Model year not really known.  But after the AC motor went out of production....

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.
