Tables with no belt change for 45's and 33's?


I have noticed that most high quality turntables are belt drive, and that you have to change the position of the belt (which is often under the platter) manually to alter the speed when you play 45's or 33's. Are there any quality tables out there that have a simple way to change the speed without moving a belt manually (which on my MMF-5 requires that you remove the glass platter)? Thanks,

The new Basis tables (or at least my upgraded Ovation) have a dual pulley on the motor, so you just move the belt to a different grove without having to take anything apart or fumble around; I seem to recall my Well-Tempered having the same arrangement(?). Far better than my Ovation before the upgrade, where you had to change the pulley using the world's smallest Allen wrench. Or you could get a Walker motor drive (or a VPI PLC) and just flick a switch, which I do now (I got it before the upgrade, I was tired of changing pulleys).
The Nottinghams have the same dual-pulley system that Rcprince mentions in association with the Basis.
The Walker motor controller works on Basis, Walker , VPI and others.

Changes between 33 and 45 without moving the belt, allows micro adjustment for the two speeds separately and greatly improves the performance.
