  OT a little, but UTC has been making transformers since Tesla was a pup,
and made a very large line of generic replacement items for basic repair
work back when electronics glowed in the dark and 'computers' were folks
who did low-level math grunt-work for insurance companies and big
engineering firms.


   Having a 5v tap means 5 volt filament recitifier tubes.. 5U4, 5Y3s
maybe... 850 V tap is undoubtedly center-tapped [is there a picture of
the label? Most UTC replacement devices had schematics on the side...]

   Sounds maybe it's a replacement unit for one of the bigger tube TV sets
from a few years (decades) back... the bigger B/W and early color sets
needed a pretty high initial DC level (B+) to drive the Horizontal amps
and HV section.

  Could also be a replacement for a Ham Transmitter from the same era.

  $103??? Well, if you needed it, and nothing else would fit... I guess
so. That was a lot of money back then.


   I'm too lazy to look up UTC and the part number on the web to see if
any reference data has been archived.

 Cheerz
