Turnable database with TimeLine

Were the TT's hooked up to any kind of speed control device?

My SME has an adjustable motor controller. The SP10 has a controller that is not adjustable. The Denon has no controller and I'm not sure about Halcro's Victor.

Makes sense in that the table is actually playing a record, though w/ a speed strobe there is a spinning disc. This is certainly easier to make out though.

Damn that Led Zeppelin IV album is warped. I would not play it without a periphery ring. Also, watching Halcro's videos, it's interesting how some audiophiles just drop the cartridge on the record. I lower my Delos as gently as I possibly can. Seems like a good practice to prolong the suspension's life.

ALL direct-drive turntables have a "motor controller" of one form or another, built in to the servo circuit. I suppose it is possible that a DD turntable could benefit from a standard AC regenerator, like a PS Audio power source, but such a device is different in purpose from a dedicated tt motor controller. You can assume that the TT101 has such a one. For one thing, the TT101 has a DC motor; the PS inside the chassis converts AC into +/-12VDC and +5VDC outputs. The Denon has a 3-phase AC motor that is "controlled" by a feedback circuit. So, it's able to adjust its speed. (I don't know whether the DP45 has adjustable speed option on the control panel, but the more expensive models in that line-up do/did.)
