Name that Transformer

[W4DNR]

Another exciting round of   "Name That Transformer"

Hermitically sealed 3.75 x 3.75 x 4.75 inches

five ceramic terminals on bottom   two to the left three to the right

markings  of  1203-005  and
underneath that 7-7 SN   

also for bonus points :

A UTC   LS-666  50 watt audio

primary  2 ohms  or 8 ohms
secondary 125 ohms  or 500 ohms

Why do I have this transformer and what can I do with it ?

Maybe drive it with a 50 watt solid state audio amp and have
160 volts @ 300 ma ??

Thanks

hi Don .... can u photo the first xfmr ?

the UTC is a line driver xfmr .... these are also known as 25 or 70 Volt systems for pa systems .... oftentimes these are not very well matched

sec 125 or 500.. Hmm. drive 3-500Z or other low voltage high current grids?
