Dear fellow collectors,

in order to bring my HMZL back to working condition, I need documentation for the U.O.R.1 universal power supply. It's an impressive device with a big power transformer, two choppers, and a whole lot of chokes and electrolytics. There is a switchboard that allows the unit to be set for a whole range of input power options, A.C. and D.C.

Unfortunately, my unit was not only repaired, but modified along the way. Some caps were replaced, some of the wiring was changed, and some resistors bypassed. I could probably fix it for A.C. operation, but in order to achieve full service for D.C. as well, I need your help. Has anyone got a schematic, or has maybe seen/worked/repaired a unit in original condition?

Your help is appreciated,

Nikolaus Loewe
