HAL BATTLER

Commentary

Monaural power amplifier designed to demonstrate the ability of the EL 156 vacuum tube.

EL 156 made by Telefunken is used for the vacuum tube.

The vacuum tube circuit as a preconceived concept was completely scrapped, and the transistor circuit technique was incorporated into the design.
In addition, we use carefully selected parts including wiring materials.

The circuit configuration is a direct-coupled DC type drive stage with two differential stages and a parallel push-pull type with four EL 156 terminals for the final stage.

Equipped with an NF control switch that can control the amount of NFB, 0dB/6dB/12dB can be selected.
