Mystery UTC, all the printing is gone. But it looks like an A-24 style case.

Here's the DCR for the taps.

Pins 1 to 3 read 29 ohms.
Pins 3 and 4 are connected together.
Pins 4 to 6 read 29 ohms.
Pins 7 to 9 read 1451 ohms.
Pins 8 and 9 are connected together.
Pins 8 to 10 read 1458 ohms.

Any idea what this guy might be?

An A24 plate to line perhaps?

at a glance looks more like an A-10.  

Thanks for that Doug.

That's good news since I was hoping for a transformer suitable for an LA2a project

The values seem to jive with another A-10 that I have sitting here.

My guess is A-26 - almost a perfect double of A-24 DCRs  w/CT


PS-  my reply was returned (delivery failed message).  Sent another via alt listing Q & A

 
measured an A-26 and got 2k7 : 89 total.  The 58 ohm side makes me think input, and A-10 by the terminals.  Don't have A-10 sec on hand, but CJ put the data somewhere.

Thanks for all the help guys.

It sure seems like it's an input since we've got about ~600ohms on that side.

Once I have it in my hands I'll run a signal/ratio test on it, hopefully that will give us some more clues.
