Seems like something nice for TTY loop power supplies.

Subject: [Milsurplus] small isolation XFMRs anyone?

If anyone needs some isolation transformers, I can latch onto several at $7
each if I act quickly over the next couple of days. These are nice
Thordarson units with 2.75 x 2.25 x 1 inch frames, 3.125 inches between the
mounting ears holes. Primary is a dual winding 115/230 V 50/60 Hz.
Secondary is 120 VCT, 0.5 amp. Part number markings are EIA 238-9509 and
CFP 618. They use solder lugs mounted on the wire spools/thimbles, rather
than wire leads. The primary & secondary are on physically separate spools
so that one can easily remove secondary turns to lower output voltage if
desired for a vintage radio. Most of the items appear unused though a
couple have cut-off leads attached to the solder lugs. Let me know ASAP if
you want me to grab some of these.
