Default "Ug" The Transformer

Triode Electronics has been offering a 30W, 1250 ohm:8 ohm (actually with 4, 8, and 16 ohms taps plus a 43% UL primary tap). transformer for ages. The primary is rated at a whopping 225 mA. Apparently, they weren't big movers, so Triode recently dropped the price on them quite a bit. It so happens I might actually have a use for something like this, so I bought a couple. First off, this transformer is BIG, weighing in at 11.5 pounds. I did some measurements, and at least with my measuring technique, the transformer primary impedance is more like 1060-1080 ohms (depending on the tap). Inductance is fairly respectable at 11.9H.

The transformers are neatly done (as much as can be done for a big, black chunk of iron). My intentions for these involve something heretical and solid state, but no doubt someone will figure out something that can be done vacuum-wise with these. Running a monster sweep tube UL connected might be an interesting experiment.

Seems like a perfect match for the ten pound power transformer...

They ship by Priority only. How much it is, for a pair of such transformers?

They shipped mine in two medium flat-rate boxes, with lots of padding.
