Utah 8441 Mod transformer about 7 inches square.

Anybody got the specs, other than figuring it by the lb.?

The secondary is marked for impedance but the P/P primary is unmarked except for plates and B+

Thanks,

Put a small AC voltage on the secondary and then measure the voltage on the whole primary.  This will give you the turns ratio.  Impedance is the square of the turns ratio.  Most likely a step-down primary to secondary.  So, you'll probably measure a higher voltage on the primary.

I don't have it my possession, but it's for sale here, misidentified as a power transformer. It's a good deal for a hefty mod transformer for somebody.

Information on Utah xfmrs is hard to come by.  Looked at the pics, It's a mod xfmr,  probably in the 125 watt class at least could be more.  Due to its age I would not pay much for it.  The listed price plus the shipping would be too much for a dubious xfmr.
