Product details
Fezz Lybra Mono Power Amplifier is supplied as a pair of dedicated 300B monoblocks. Each unit uses a parallel single-ended Class A circuit with two 300B output triodes, producing a rated fifteen watts for one channel. Two independent chassis provide the left and right channels of a stereo system.
300B output with valve rectification
Each monoblock combines its output triodes with two 6SN7 valves and a valve-rectified supply. Fezz’s toroidal output transformers provide separate four- and eight-ohm speaker connections. Automatic bias adjustment and a warmup-delay circuit prepare the output valves for operation without routine manual bias setting.
Preamplifier connection and finish choices
RCA and XLR source inputs are selected at the rear panel. A separate line preamplifier or source with a suitable variable output controls listening level. The pair is available in seven Evolution finishes, with matching finishes across the supplied pair. Output, consumption and physical measurements are specified per monoblock rather than combined for the pair.
