for sale is a pair of Brand New in the Box (new old stock) UTC HA-133
transformers that has never been used or hooked up. They are only tested
with the LCR impedance meter and an oscilloscope to ensure they works
100% perfect. A temporary jumpers are soldered before to measure all the
coils in series so some traces of the solders may be found. But they
are never used otherwise.
There is no OPEN or SHORT turns on these transformers and test results indicate they are matched pairs.
transformers are gray potted case but they are made by UTC in different
batches. So, one transformer has a little darker grey color than the
other which has a lighter grey color. But they are electrically and
functionally the SAME!
These are ideal transformers for the
single ended line stage preamp using 26/01 tubes from Kennedy (google
Kennedy 26 if you are not sure what I mean).
Primary has 15000ohm impedance and it can take up to 8mA DC bias.
Secondary has 500 (600), 333, 250, 200, 125, 50 ohms impedance for the Line Output use.
They were made here in the Good Old U.S.A!
