Hi All.
I have acquired one of these units in good order but have power supply problems. The PSU circuitry is different to the only circuit information I have been able to find - a problem identical, I think, to a previous poster on this forum. The /5 seems to indicate a different model in a number of areas.

I have seen references to a Marconi Instruments Yahoo group but haven't been able to find the group using the Yahoo search tool. Does anybody know if the group still operates? and if so where it can be found.
Many thanks
