Looking through the parts list there is something
I'd like the list's
opinion on. The diagram shows a transformer but the list says
"REGULATOR ASM, FERRORESONANT-60CPS 120VA" and a similar option for
50Hz which of course I don't have. What are these for? Might they work
at the wrong frequency?
A ferroresonant transformer will not work properly at the
wrong frequency.
Will they be damaged or just not work?
I
don't think the transformer will be damaged, but it won't regulate
properly. Maybe someone else here that knows more about ferroresonant
transformers can provide an explanation of the results.
At CHM, the IBM 1401 restoration team had the same issue when restoring
a European 1401 in the US. They decided to get a power converter. (I
don't recall whether they got a rotary converter or a solid-state inverter.)
This is part of a 48v DC supply. Should I build a
simple 48V supply
myself or even see what I can find in my verifier spares?
Yes, replacing the power
supply is probably your best options.
