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


Back in 2003 I purchased a used Michell Gyro SE from a fellow member on Audiogon.  Excellent table, excellent design.... 

About a month ago the speed of the platter increased; way faster than 33 1/3.

I've sent multiple emails directly to Michell in England, but alas, no reply.

I have not tried to call them directly, and may try to do so.

Does anyone know of anybody or any company in North America that can provide service for J.A. Michaell turntable?

Thank you in advance for your help!

Hi Quincy,

The Gyro SE is a beautiful little table and nicely designed. I do not know what kind of motor it has but I suspect it is an AC syncro motor. If there is a problem with the belt drive the speed will become irregular and if bad it will slow down. Some AC motors are driven by an oscillator which if malfunctioning might cause the speed to increase. Speeding up is unusual. Does the motor have a speed adjustment? Look at the manual online.  If it does not then the motor would need to be sent back to Michell via it's US importer fidelityimports.com. I suggest you get in touch with them

For what it's worth--I had a similar issue with an Ariston table.  The platter was spinning really fast and kept speeding up.  I took the table to a local stereo repair shop and the problem turned out to be dirty potentiometers in the speed adjustment circuitry.  They cleaned the pots and all is well.  Maybe relevant, maybe not.

I think the first thing you should try is replacing the belt. My Basis is very speed sensitive to different belts. Worth a try at least. 

Try the belt first. Does your gyrodec have the older ac motor or the newer (post 2000?) dc motor? This link may help. https://www.angelfire.com/music5/michell_gyrodec/

My dc motor has a speed adjustment.

Hope this helps.
