I´ve dealt with Ray at CTC before, and found him a great chap.

He´s got these: http://www.classichifi-shop.co.uk/pr...upply-unit-psu



Should do what the rest of the pinnacle products do, but at slightly lower cost it seems.

Anyone knows anything about them or perhaps even tried one ?
Looks interesting and stylish, and priced in the same area as Martin Bastin's PSUs. I use a Martin Bastin PSU with my Thorens TD-124, but I don't think it's wise to do speed selection entirely electronically like this, since you're then asking the motor to run across a very wide speed range; and it probably won't like that. Furthermore, I've found that these old shaded pole motors do seem to work best when a mere touch of eddy brake is applied (Martin Bastin did tell me why this is a good thing, but I discovered the fact by listening). I also discovered that idlers can easily lose their sonic 'drive' if the supply voltage is lowered too much, so in practice it seems to be better to set voltage relatively high at 220-240v, apply a touch of eddy braking, and then tweak the supply frequency to get correct rotational speed.
