Lenco and Garrard external ac power supply

Been thinking about this recently...Does it even make sense to try to find someone willing to build a power supply for turntables such as the Lenco L75 or Garrard 301 when they were made to just be plugged directly into the wall ac in the first place??

Loricroft makes ones for the 301 that convert ac to dc then back to "perfect" ac again which is what something like a Pure Power ac line conditioner/regenerator does. The neat thing about the Loricroft is that you can apparently adjust the 301's speed with it. It would be trick to find something like that for a Lenco 75 that was not so expensive.

PS audio used to make some big line re-conditioners that did the same sort of thing I think back in the day but I don't know if they are making the same equipmnet still. Furman and a couple others I think do similar things also.

What would be neat would be to find a ac regenerator that you could use to control the speed of either a 301, 401 or Lenco 75. Since they are all AC and can run at 110 or 220 volts maybe its possible, I don;t know but I know the Loricroft controller is way way expensive is it really worth $4000 bucks?? Thats almost as much as a restored 301 or top Lenco....geesh

Maybe you could just save the 4000 bucks and build one??/ Could it really be that tough?..

I think Jean Nantais is playing around with designing an external PS for his Lenco rebuilds. You could query him.

When I had a VPI TNT Mk. II, I found that the SDS controller/regenerator was essential to optimizing its sonics. I figured it would be equally essential with the Nantais Lenco that replaced it (replaced in turn by another 2-arm Lenco).

Turns out, the SDS didn't do a thing for the Lenco. Nothing. Zip. The Lenco sure beat the TNT in every way that's important to me, but I couldn't tell a bit of difference whether it was plugged into the SDS or directly into the wall. I'm not sure what that proves, and I certainly wouldn't second-guess Jean's ability to come up with a better PS, but I wouldn't expect it to be cheap.

You can get good used deals on the original PS-300's from PS Audio. They were one of the first regenerators and will do the trick. At one time I bought a deluxe motor controller from Walker Audio and after conducting A/B listening tests could not hear the difference with the TT plugged into the PS Audio or the Walker.

I currently have a Nottingham Ana-log with its own stand-alone motor controller. Again, I did A/B testing with the PS Audio and could not hear a difference. Maybe I lucked out and have decent power that does not need much conditioning.
