George, with 50hz pulley still can't compensate the speed using the pitch control, though you can zero in on the strobe markings but still too fast. One alternative is to shave down your existing 50hz pulley to 5/6 of what it is (have a caliper to check the measurement and a strobe disc to verify speed)This route may even be a lot better than the ones you can get thru ebay. The pulley measurements for the 301 and 401 are actually the same though the orientation of the locking screws are different.
Crem1, those slate plinths are real beauties but as you said they do cost a bundle.
Lewm, I have heard a lot of good things about them Lenco's. I also have a 301, somehow if my memory serves me right the 401 seems to be heavier( Unless my mind has been playing tricks on me)could be due to the heavier motor. Just too lazy to check it now.
