Lenco and Garrard external ac power supply

A PS Audio P300 doesn't do a thing for a Lenco either (had one, plugged the Lenco into it, no real difference). Too many negative stories about Jean? I've known him for almost a decade. and, yeah, he's opinionated and can come off as arrogant. I'd steer clear of him if I were you :-)

I will steer clear of nantais, but been warned already, but thanks though for your advice :) Arrogance is often mistaken for knowledge, which in my life experience is misconceiving. In actuality, those possessing true knowledge have nothing to be threatened from, hence their lack of blatant arrogance. Humble knowledge wins every time over arrogance, at least in my opinion. ymmv as they say...

Here is the thing, guys. The SDS and Walker Audio Motor Controller, and probably the PS Audio thingie, would not be expected to do anything for the Garrard or Lenco motors (apart from if you really do have noisy AC coming in). This is because at least the first two products are designed to control AC synchronous motors. The Lenco and Garrard motors are induction type motors. Mark Kelly showed that if you control such motors by reducing voltage, you lose torque until finally at a low enough voltage the torque falls off a cliff (no torque). Whether or not they can be controlled by AC frequency, I don't remember, but since they are not "AC synchronous", purely altering frequency is unlikely to be the solution. I think you have to control both voltage and line frequency. In any case, designing a controller for these motors is a specialized task. Mark Kelly was designing one, but the project is in limbo, at best. On Lenco Heaven there is a long term project to develop a controller and printed circuit boards, I think, will be sold to those who sign up. I have been wondering about the Loricraft, whether it is truly designed correctly to run an induction motor.

I don't see how it could hurt to use a PS Audio or other power regenerator in front of a Lenco or Garrard, if you have noisy AC, but don't expect miracles.

FWIW, my experience is identical to Dave's with his SDS; my Walker Motor Controller, which worked wonders with my Notts tt, does absolutely nothing for my Lenco. In fact, I took the Walker out of the way, because I think the operation of the motor was a touch less good with it vs without it.

Jeremey72, since you seem to value "humble knowledge," would that not preclude prejudice, which is presumed and prejudged knowledge, and not at all humble? Lots of people have agendas and opinions. Certainly Jean has his, and he's a character. But he's a good character, in my experience, and has gone the proverbial extra mile in all of my dealings with him. But then, I approached my interactions with him humbly. YMMV.

I too have had dealings with Jean. My experience was mixed. There was some good and some not so good. But I did not come away thinking he was a bad guy. Sometimes he over-reaches or makes claims that just do not hold up to close inspection. He built up a Lenco in CLD plinth for me. Two tonearm mounts, etc. I had several issues with it upon initial delivery, some of which could have been due to shipper abuse; some not. I had to do the trouble-shooting myself. But eventually we resolved all issues.
