Hi John,
This is a little off topic , I would like to ask you because I know you own a SOTA Millenia turntable. My friend bought a preowned Millenia and he wanted to know how strong the vacumm/suction for warped records. The guy had Luxman turntables in the past w/ vacumm / suction capability & he noticed that the SOTA has lower vacumm power but the vacumm motor was very quiet & he can barely hear the vacumm motor.

Hi Mondial,
I've never measured the vacuum on my SOTA Millennia, but it is specified to provide LP clamping vacuum pressure of 3.0" Hg, +/- 0.2" Hg. This equates to a vacuum of about 1.47-psi.
There are actually two vacuum intensities when you initially start the turntable. It sucks the record down with higher vacuum and then switches to low vacuum so as not to damage the record. If there are any leaks around the seal on the record, you will hear a relay in the vacuum pump clicking continuously. It is switching back and forth between high and low vacuum. When you have a good seal, the vacuum pump switches to low vacuum immediately and remains there.
Yes, the vacuum pump is virtually silent, especially when placed on a carpeted floor. It can be sitting right next to the turntable and you won't hear it. I have no idea how it compares to other vacuum pumps, but I rarely find a record that is too warped for it suck down. When I do, I simply place another LP on top of it and when the vacuum takes hold I stop the platter and remove the top record. The vacuum on mine always holds long enough to stop the platter and start it back up again.
If your friend doesn't think his turntable is working properly, he should contact SOTA. It's possible the platter seal needs to be replaced. Mine is 12-years old now and I sometimes notice the relay in the pump clicking. When I clean the rubber seal it stops. I probably should have the platter rubber seal replace on mine one of these days in the not too distant future.
Best regards,
John Elison
Thanks John I will relay your message to my friend.
