EL84 Push-Pull 10W Output transformer 8000 Ohms 43% UL taps (Mullard 5-10)

Description

A high quality 10W at 20Hz Push pull ultra linear output transformer. Designed for the Mullard 5-10 amplifier but may be used in any single ended design with a valve having an output impedance of 8000 Ohms anode to anode, such as an EL84.

This is similar to our 6600 Ohm 20% ultra linear tap design, but results in an improvement in distortion of around 0.1% as described in the Mullard “Circuits for amplifiers” book.

Primary

Multi section winding, for reduced leakage inductance.

Inductance

Inductance 35H at 25Hz.
