Quadfiler 1:1:1:1 matching transformer.
Availability: Product is built to order.
Ship date: 8 weeks
$29.62

Design
Mathematically designed to produce a turns ratio of 1:1:1:1 for line level signals.

Primary/Secondary (Input/Output)
The transformer has four identical windings with a maximum voltage of 7.5Vrms.

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.

Sheilding
This unit has an outer copper shielding around winding and core to help eliminate outside interference.

Termination/Mounting
This unit is designed for printed circuit board mounting. For footprint and suggested hole and pad size please see the dimensional drawing.

Excellent quadfilar output transformer at a fair price
As a long-time audio engineer and recordist, I've mostly used higher-priced output transformers from Cinemag, Jensen, UTC over the years and more recently from Ed Anderson. While I still love all the above, I've found that I can match the performance and sound that I need while saving money with this XS4400 quadfilar wound transformer.
They measure great with 1K square waves, but the real test is how they sound. I wouldn't hesitate replacing Ed's (really good) 2503 with these, if you need to save a few bucks. I've successfully tried these with API 312 type circuits as well as custom mic preamps. Mostly clean, but with some of the nice iron flavor that we all love.
Try 'em; you'll like 'em.
