Title: Anybody know the specs on a Utah 8441 Mod transformer? Post by: N0WEK on May 16, 2017, 08:42:42 PM 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, Greg Title: Re: Anybody know the specs on a Utah 8441 Mod transformer? Post by: KA2DZT on May 17, 2017, 09:17:38 AM 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.

Post by: KA2DZT on May 17, 2017, 04:58:42 PM 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. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
