Jensen Transformers JT-123-FLPCH Line Output Transformer
1:1 or 1:2 ratio with quadfilar windings, 50% nickel laminations, +21dBu @ 20Hz, PC board mount
Jensen Transformers JT-123-FLPCH Lline Output Transformer
The Jensen Transformers JT-123-FLPCH Line Output transformers allow any output stage circuit topology, whether balanced or unbalanced, to drive any equipment input, whether balanced or unbalanced,
without regard to special connection rules or specific cables. Due to the isolation they afford, hum can be substantially reduced.
It may also be worth mentioning that JT-123-FLCF is a direct replacement for
JT-112-LCF – the only change is the part
number
.  JT-123-FLPCH is electrically identical to both of the above, but with PC board mount instead of wire leads.
Here are some key specs:
Impedance ratio: 600:600
Turns ratio: 1:1
Maximum 20 Hz input: +20 dBu
THD @ 20 Hz: 0.025 %
Frequency Response: 20 – 20 KHz,  -0.04 / +0.04 dB
See spec sheet for additional details
With inferior products coming from all over the world, we think it is a genuine treasure to find a company like
Jensen Transformers, actually designing and manufacturing some of the finest products in the world, right here in
the USA, and we are proud to be able to offer their products. The JT-123-FLPCH is made in the USA, is backed by the manufacturer’s
comprehensive one-year warranty, and has a remarkable 20-year warranty on the transformer device itself.
