Secondary (Output) Impedance

$35.08

Qty:

Design
Mathematically designed to produce exact plate and screen voltages.

Primary (Input)
The input is designed for a 7.6K 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 0.187" (3/16") quick disconnects.

Mounting
This unit comes with zinc plated channel/frame for mounting with the use of two screws.

Great transformer for small-to-medium-sized guitar amplifiers

I selected this transformer for a self-split push-pull 6V6 guitar amplifier. My first choice was the GXPP15-4-8K because of it's physical appearance, but I wanted a higher power rating (on paper, my circuit was good for 14 watts, and I prefer to specify transformers conservatively). I don't regret my choice one bit ... the XPP25-4-7.6K has performed very well in my application with only a couple of minor adjustments to account for the lower DC resistance of the primary winding.
