Secondary (Output) Impedance *

$24.77

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 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 bargain OT!

I've been using these in my small 'Sloppy Amps' series guitar amps and am very pleased. Lately I needed a 'shop amp' and used a low rp triode with these transformers. I got absolutely fabulous sound, bandwidth flat from 15Hz to 55kHz! Although distortion rises below 50Hz on the measurements, I cannot hear any difference between these and my 100dollar transformers in my HiFi amp.
Great for the price!

Love it!

Used this OT on a modded Gibson GA-5 circuit and it sounds great. Seems the more I play it the more I like it. For home, it is my main amp.
