I have just been given one of these - well, rescued it off a pallet destined for the skip actually - reportedly not working and with the mains lead cut off.

I haven`t actually tried it out yet and probably won't have the time for a while but it would be interesting to know if anyone knows anything about it or even has a handbook or a circuit I could get a copy of.
