Design
Mathematically designed to produce the specified voltage(s) when loaded.

Primary (Input)
Designed for 120V, 60Hz.

Secondary (Output)
This transformer has multiple voltage windings, 290V at 250mA and 6.3V (3.15-0-3.15) at 4A center tapped.

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 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.

What a difference this PT made!!!


I don't claim to understand the physics of power transformers thoroughly but what I do know is results.  I replaced a bad power transformer in an amp with a Hammond, very similar to this one.  But I thought something must be wrong because the Hammond was getting so hot and the current draw was not even near their limit about 1/2 of the limit.  When I used the Edcore PT it stayed cool and just barely got warm to the touch.  Why?  I don't know, but I like a transformer that remains cool during operation rather than too hot to touch more than 2 seconds.
