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

I will do that! rhg3!

It is unlikely that a motor would cause speed problems, it could be the DC power supply that is causing these problems.
Changing the engine with the risk of solving nothing and throwing away a lot of money is the worst option.
In old Gyrodec like mine the speed problems were usually attributable to a small ceramic capacitor located in the motor but easily accessible and replaceable but they were rare cases and relegated to Papst motors operating in AC... for this reason I would look more at the power supply than to the motor in the new DC

It’s quite amazing that this is supposed to be a higher end turntable and the manufacturer is not even bothering to respond to your emails(?). I would say that is not a sign of being a high-quality manufacturer. After all, what you do expect, reasonably, from higher-end brands is great service and a high-level of customer service responsiveness.

Greetings Friends!

I did receive the new DC motor and controller from Mike @ the listening room.

The instructions were concise, but required cutting wires and then soldering wires near critical electronic components. All this to get a new hook up. I took another path, which was to drill out the motor housing hole which allows you to pass thru the 7/16" connector plug. If you look at the photo album attached below via Google Link you will see what I’m talking about. It worked just fine!  

New motor ran a bit fast, but I adjusted it with my Cardas Frequency Sweep record with strobe label. We are back in business, but ~$700 poorer. Still less expensive that purchasing a new high quality table. As a side note, anyone know of a company that could look over my old motor controller and see if they can repair it. Would be nice to have a spare....

Be good, take care!

Nice work!
