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 2.5K 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.

Monster SE Transformer
I built a 2A3 SE amp using this transformer. I bought the 4 Ohm version. The frequency response is from 14Hz to 27kHz. No too bad for a 25 watt beast such as this. Bass is phenomenal as you would guess. Unless you need 25 full watts of power handling, I would buy the 10 or 15 watt version and get better high end bandwidth. Still an excellent sounding transformer.
