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.

I'd have to guess that you have a thermally related issue - power on, current draw, and component 'X' drifts out of spec. Tracking this proverbial needle in a haystack can be very frustrating without a working knowledge of electronics. That said, in most cases semiconductors either work or they don't; it is pretty rare to see a fixed regulator, for example, start drifting wildly on its own - if that occurs they simply self-destruct. I'd look to passive components first - capacitors and carbon comp resistors, especially on the raw power supply/rectification side of things. Good luck.
