DC motors and outboard power supplies...


For those of you with analog rigs that utilize a DC motor and outboard power supply....I'm wondering:

1. How often do you check to see if the platter is at correct speed?

2. How often do you have to fine tune the speed adjustment?

3. Once fine tuned, does it stay throughout the listening session, or do you need to make adjustments throughout?

4. Would you be willing to comment on which table you are using?

Thank you for your comments.

1. About once a week or after a long time off.

2. Very rarely.

3. It plays at speed during the listening session and for many, many days, but I check it from time to time anyways.

4. I'm using the Acoustic Signature Mambo. Its bearing is self-lubricated, so it does not use oil. The bearing is made of a material called Tidorfolon, which, as I understand it, is composed of offerrite, vanadium, teflon and titanium. The outboard Alpha power supply generates its own frequency and therefore is not affected by power fluctuations.

Best,
