If you have a rebuilt Garrard or Lenco you need this!

I have been thrilled with my Woodsong Garrard 301. Robin at Robyatt Audio suggested that I get a LDA Power Supply.
These change from 60hz to 50hz and, most significantly, up 110v to 220v. The motors on the Garrards and Lencos were designed to run on 220v. When fed the right power. it is transformative. 
They said it would be shocking. I agree! Now that the motor has 220v and 50hz, the music has a hold on it that is revelatory. It is most shocking in piano. What was before ok and kind of old sounding now sounds more like a piano that I have heard from my system. And the bass is amazing. Strong, clear and tight. 
You have to make a couple of simple changes but not very difficult. These are about $1K but so well worth it!

Yes, you need to get the 50Hz pulley and change the jumpers on the wiring block. There are four poles with 2 jumpers on the two on the sides for 110v to one jumper to the two center poles for 220v.
It is a little tricky to make sure the idler wheel only makes connection on the lowest notch of the pulley. With the PS you change between 33 and 45 on the unit with a switch. There is also a variable speed control there that can be locked with a switch on the back. The improvement is huge.

I have a 401 that is NOT converted. It is still 220 and has the 50 hz pully.

401 anyone? 

I'm a Thoren guy, and for rim drives Russcos, Sparta, QRKs..

Good to know though.. I think I have a 301 somewhere. 401 was the better of the two.

Weird a Zero 100 was the best looking and WORST sounding of the whole bunch.. I have one all dolled up.. Just like my Victrola..

I think I'll stick to my Phoenix Engineering combo on my Nantais Lenco. Holds speed within .01 rpm. But good to know there's another excellent option out there.

The LDA power supply is an AC regenerator similar to the one Monarchy Audio and CTC Turntable used to carry. It should be excellent in lowering Garrard motor noises allowing the motor to run smoother and quieter, this is audible if you put your ears close to the platter. With certain music, the improvement is really drastic, with other music the improved motor made music not sound as immediate. The Garrard seems to have lost some of the drive that Garrards are known for. I'm not against or in favor of AC regenerators, just pointing out both sides for you to consider.
