The Joule Electra VZN-80 mkIV Emerald is a highly regarded output transformerless (OTL) stereo power amplifier utilizing a Circletron topology with eight 6C33-CB output tubes and ten driver tubes. Known for its exceptional tonal purity, palpable soundstage, and dynamic performance, it features upgraded circuit boards in later MK V versions, wood-based non-magnetic chassis options like Musicwood, point-to-point wiring, adjustable feedback and bias controls, and a Variac for optimal filament voltage. The company ceased operations around 2013 following designer Jud Barber's retirement, with his passing in 2022, making new production unavailable.
