It's been suggested that the high pole brushless dc motor from a washing machine could be used.

People use TT's with anywhere up to 12kg-cm or torque.

Hello Nickou,

What is the use of a modern dc motor as long as the Lyrec hasn't gone down ? You still have to use the same coupling shaft and the same oil dashpot so there won't be an improvement on the rumble figure and tightness of the low end like you get with the Technics motor drive.

What's wrong with the Lyrec motor? If it's in good condition and hooked up correctly there shouldn't be any problems. And the Technics motor is unobtainable anyway - no need to spend time fantasizing about that one.
