Secondary (Output) Impedance *

$99.39

Qty:

Design
Mathematically designed to produce exact plate and screen voltages. These transformers are precision gapped to adjust for unbalanced DC current.

Primary (Input)
The input is designed for a 5K Ohms impedance source.

Secondary (Output)
The output is designed for a specified speaker impedance.

Magnet Wire
All units are wound with the finest virgin copper magnet wire. All windings use heavy insulated wire to provide excellent manufacturing yield, lower customer cost and superior life.

The Core
EDCOR uses the finest M6 line grain oriented steel cores. Each unit is hand stacked to assure at least 92% stack.

The Bobbin
EDCOR's standard bobbin with black finishing tape.

Termination
The terminations are UL1015 20 and 18 ga. lead wire.

Mounting
This unit comes with steel end bells for mounting with the use of four screws. The end bells are powder coated Gentian Blue (RAL 5010) to add to your tube display and overall appearance.

Delicious sound

Used them in a RL12T15 stereo amp with 500volts at plate. Driver is D3a (german Post and WWII tube mix) The sound is incredible!!! Rich details, lots of bass and clear and transparent voice reproduction. Sometimes my amps take place in competitions and shows. They always win...
I am just ordering more of this stuff now.
Thanks Edcore :-)

Highly Recommended!

I think Edcor transformers are the best value in terms of cost and performance. I am never disappointed in their products. The CXSE transformer paired with the 45 power triode produces amazing sound. You can check out some of my DIY projects at https://www.vacuumtubeaudio.design/
