What's your SDS setting?

60.35 for HRX with rim drive and superplatter.

Stringreen,
Why did you change from the Superplatter to the Classic platter? Can you give some details as to their sonic differences? I presume your glad you changed?

65.75

BUT many years ago the rubber cable broke on my original Aries and I replaced it with a double run of fishing line.... Works great and maintains a constent 33.3

65.75? Holy cripes! I was told silk thread renders sonic benefits on VPI tables, but since you cannot move the motor on the Classic to adjust tension, silk threads or fishing lines will not work. I saw an A-gon member using the Teres speed controller/motor with a mylar belt with his Classic, which I guess is a very advanced option, but otherwise the rubber belt is it.

Regarding different settings for different platters, I think I might just send an email to VPI so that they can hopefully clarify it. I don't have engineering background, and I might be misunderstanding the role of the SDS, but it seems to me that since all VPI tables are fully functional and quite accurate without the SDS, it should not matter how many belts, flywheels, or what kind of platter you have as far as the SDS setting. It should ideally be as close to the standard 60 Hz as possible, and really used as a fine tuning tool, rather than a full-blown replacement for the power supply. Reading the manual, the SDS is more about the stability of the power than changing it.

If your current has a frequency of 60 Hz and you need 65 Hz to get your platter to spin at 33 1/3, your table would be useless without the SDS, which would be absurd. Less than 2 Hz makes a tremendous difference in the speed of the platter, and can easily be heard. I just don't see how this can be reconciled unless there is a serious anomaly in the power supply.

From my frustrating experience with lubricating the bearing on my Classic, it became quite clear to me that the platter needs to be optimally lubricated so that the SDS is not used to force the motor to work harder to counteract the resistance within the bearing, rather than simply supply a stable current to the motor. As the lubrication settled, the SDS is now set to 60.25 Hz as opposed to close to 62 Hz when I first used the bike grease. Both settings resulted in the perfect speed, but obviously the motor had to work much harder to maintain 33 1/3 rpm at the higher setting. That transferred to the quality of the sound.

If anyone has a deeper understanding of the SDS, please chime in.
