Equipped with the highly regarded 845 power triode
and is capable of delivering up to 20 watts of power
into a 4, 8 or 16 ohm load. The zero-feedback circuit
incorporates an extraordinary single-stage driver
topology employing two EL803S power pentodes
operated in triode mode. The driver stage is so powerful
that it could (theoretically) drive a loudspeaker
with ultra-low distortion on its own.
The amplifier is entirely hard-wired, while every detail
of the internal construction has been given carefull
attention to ensure reliability and ease of service.
