Feb 1, 2015 · EL34 Push-Pull Mono-Block Power Amplifiers. This amplifier was featured on the January 2003 Issue of the "High-Fidelity Audio: Radio Technology" by Mr. Tadaatsu Atarashi. The purpose of designing this amplifier was to drive the B&W Signature 800 with 70W maximum output derived from EL34 Push-Pull Class B1 fixed bias operation.

The EL34 is a thermionic vacuum tube of the power pentode type. The EL34 was introduced in 1955 by Mullard, which was owned by Philips. [1]
