The power supply (500S) for my Multigrade head has just died. Does anyone know of either i) where to buy one, ii) anyone who repairs them in Europe (the closer to Norway the better as it weighs a fair bit, but the UK would be fine too), or iii) where to obtain wiring diagrams?
I also had problems with my power supply.
Check the fuse, and if the fuse is ok check if by fiddling around with the fuse-house (pushing it in his fuseguide) you can get the power back on.
Mine had a fault in the fuse-box/voltageselector.
With the wirediagram you can bypass the fusebox/voltageselector and put a new fuse in the line.
I remember vaguely about a problem with fragile cabling in the 500 power supplies. It might be worth attacking it with a multimeter to check there are no broken wires in the unit.
Knowing the weight of the PSU, it'd be worth trying before shipping in or out of Norway ;-)
