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.

Dear No regrets: Looking at your thread and that in other one ( not yours ) you ask the same: Could I assume that you have speed " problems " with your TT?, do you? or which is the real subject: only curiosity?

Regards and enjoy the music.

Dear No regrets: +++++ " Literally around the world in just over 8 hours time thanks to my Linn LP12, Naim ARO, Wood bodied Benz, and Pink Link DC Battery Power Supply. " +++++

well, I'm not the right person to help you on that Linn configuration but I think that you could obtain a very good advice/support from either LINN directly or the LP12 owner " excited " community, good luck.

Regards and enjoy the music.

Dear No regrets: Normaly a speed TT has to be fix ( by design ) on 33/45rpm on the electronic circuit in the PS and normaly too this could be through a " pot " ( variable )that is the part that makes that job and for check about you need the diagram or a technician if you can't do it. I don't know how this works in your TT but you can contact to Linn and Pink Triangle and ask about.

Dear No regrets: Ok, check what Lew suggest.

+++++ " My supply does have variable pots to fine tune the speeds for 33 and 45. I can get the table to spin correctly, but then for no reason at all it justs slows way down. " +++++

I don't know which kind of pots your TT has but from what are my experiences about and taking in ount what you posted: +++ but then for no reason at all it justs slows way down... ++++, maybe there is something wrong there because that kind a problem is a sign that a pot could be going out of specs and with the working time in the future that problem could be worst.

Btw, have you the trouble in both speeds?, if yes then I think that maybe is not a pot because it is almost imposible that both suffer a damage at the same time.

Now, for any one could to have a precise diagnosis it is desirable that the check-up on your TT have to do it when the failure is present.

I can't say nothing more except: good luck.

Regards and enjoy the music.
