I have a Technics power amp SU-Z45 in the shop that has an open primary winding on the power transformer. There is a spare (not connected to circuit)pin coming out of the transformer which has continuity with one of the primary winding pins. I am wondering if this spare pin could possibly be the pin used in Europe for 220V AC power? If so, I might be able to connect the amp up with a 110V to 220V step up transformer and use the 220V winding in the amp's transformer. Does anyone have any info on this model? Does the primary winding have a built in thermal fuse? What are the secondary winding output voltages? THanks for any help. I found photos of this amp on the net.
