Garrard 301 & Thorens TD 124 voltage


Hi all,
I have a few questions and hope you can answer for me:
1. My Garrard 301 , which runs on 120V and has 60Hz pulley, still run fast with the speed adjuster turned all the way down. Beside having the diameter of the pulley reduced, is there any other way to correct the speed problem? Would reducing the voltage or altering the main frequency have any useful effect without compromising the torque of the motor?

2. With the Garrard 301 and Thorens TD-124, does running these decks at lower voltage (100V/60Hz vs 120V/60Hz) yield any benefit (ie. less motor heat/vibration/wear) without compromising sound quality and/or damaging the decks?

Thank you very much in advance.

I would assume you have a british version, which would be designed to run at 50 and not 60 Hz. If the motor is an AC synchronous (I assume it is) this would cause it to run approximately 20% faster than it should.
My bad, I did mean asynchonous and not synchronous.

I suppose another option is to get ahold of a variable frequency drive. These are used to control the speed of pumps etc..., but if a small version could be found you could easily use it as your motor speed controller. Esssentially it allows you to control the voltage frequency, and hence the motor speed.
