[time-nuts] Austron 1250A

Ole
I will guess that without the pack the bus voltage may go high and that
they also used the pack as a filter cap. So you should be able to find a
free manual on one of the sites. KO4BB is a good guess. It may be as simple
to start as a 10,000 uf cap to get going. The oscillating relay may be 60
Hz.
Best of luck those are nice units.
