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 300K 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 royal blue 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.

High quality yet affordable
I used this transformer for amplifiers running  the exotic 6C33 output tubes and paralleled 6AS7 output tubes.  I called Edcor for the special order since few of the competitors had transformers in this impedance range, and  when they did, the prices were astronomical.  It is gratifying to see that Edcor now has these affordable quality units in their normal product line.  The quality is outstanding - I am amazed at the breadth of the audio dynamic range - the music is simply scintillating!
