Mathematically designed to produce exact plate and screen voltages. These transformers are precision gapped to adjust for unbalanced DC current. Direct replacement transformer for the Fender signal ended output transformer model 25A35A, 022905, & 125A3A.
The input is designed for a 7K Ohms impedance source.
The output impedance depends on model.
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.
EDCOR uses the finest M6 line grain oriented steel cores. Each unit is hand stacked to assure at least 92% stack.
Injection molded Nylon 6/6 with the addition of 30%-35% glass fibers. The addition of glass fibers allows a higher heat deflection temperature and it brings the material to a class HB UL temperature classification.
The terminations are UL1015 20 ga. color coded lead wire around 15 inches (38cm) long.
This unit comes with steel zinc plated channel/frame for mounting with the use of two screws. See dimensional drawing.
