Also thanks for the information, I was looking for a supplier of the power connections, as one of mine had damaged leaf contacts below the tumbler, and I have linked the voltage selector out.

Just for information, and may be as a result of someone replacing one in the past, I have two 7150's, one is badged Enertec (french) and the other Solartron.

The input connectors are slightly different (they look identical), as the tumblers are configured differently (not interchangeable, though they would fit), with different voltage markings.

In addition the wiring to the two transformers are not identical, with different colour coding, and different resistance measurements.

I think the Enertec one had more wires, but if I recall correctly this was due to the interrnal windings being four independent windings, and no internal tappings. I would need to open it to check.

The wiring configuration between the two connectors was definately different, even thought the connectors looked identical externaly!
