Help VPI SDS Issue

I took the plunge and got the SDS. Wow what a difference but I am having an issue. (I am using the 600 rpm motor) In order to get the motor to spin the platter I have to push it to start it moving. The motor is on but it sound like to is hesistating. I unplugged the SDS and no issue it starts right away. Is this an issue with the 600 vs 300 motor?

Tfkaudio-

If I'm not mistaken, the only voltage adjustment available for the SDS is for the 'steady state' voltage, i.e. the SDS always starts at 115v (for maximum motor torque), and after a few seconds drops to whatever 'run', or 'steady state' voltage you've selected (for a more quiet motor).

I've got a feeling that the issue is the 600rpm motor-I've never had a problem with my Aries 2.

Interesting question Tfkaudio-

I've always just left the motor switch 'on', and turned the tt on with the sds.

However, *for the sake of experimentaion*, I tried it as you described-motor switch off, turn on SDS-and the SDS almost *immediately* jumps from 115v to the 'run' voltage. Whereas, with the motor switch on, turn on the SDS, it takes about 5 seconds for the voltage to drop.

The sds was apparently designed to have the motor switch on at all times.

*Now we know!* (-:
