[AMRadio] Need Info: UTC E-3717 and Military SB-2244/UG

[Merz Donald S]

I'm looking for information on the following.

INFO NEEDED: UTC audio transformer E-3717. This is cylindrical with chassis mounting tabs on the bottom. It is 4.5 inches in diameter and 5.5 inches tall. It weighs about 8 pounds and has 13 solder connections on the bottom. Any help identifying this and its connection diagram would be appreciated.

INFO NEEDED: Military patch panel (for teletype) SB-2244/UG. This is a gray box maybe 14 inches tall and 6 inches on the sides. The front panel is red. Beautifully-built. This looks like a TTY patch panel with loop metering and adjustment, set jacks and so forth. But any real information on this would be greatly appreciated.

Thanks for looking.
