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.

Here is what I do: I turn on all the equipment for at least 30 minutes; including my Galibier SE. I check and adjust IF necessary before the 1st LP. Then I recheck and fine tune if needed on the second LP. The bearing oil needs to warm up. I have never found that I have to readjust but I do occasionally re-check during a long listening session.
No Regrets; I find that since my rig is in the basement there is a wide variation of ambient temperature. Being so affects the bearing oil temp until it has reached a stable temp. I live in the Colorado Mountains. I do find a more measurable need for checking speed accuracy during the winter months then I do the summer months (which are few)!
