About the WAVAC Audio EC300B
The WAVAC Audio Lab EC-300B is a high-end single-ended triode (SET) stereo power amplifier renowned for its natural, emotional sound using the legendary 300B power triode. It features a patented Inverted Interstage Transformer Coupling (IITC) circuit that cancels DC magnetization for superior bass performance and harmonic richness. The design includes all direct-coupled circuitry without coupling capacitors for maximum signal purity, DC-supplied 300B heaters to minimize hum, and five proprietary transformers (one power, two IITC, two output) wound in-house to WAVAC specifications with TANGO. The chassis is 10mm thick NC-machined solid aluminum in champagne-gold finish, with Teflon tube sockets, gold-plated jacks, power line filter, perforated cooling plate, and glass canopy for output tubes. Tube complement includes triode-wired Western Electric 435A input tube, 6L6GC drivers, and 300B outputs (options like WE 300B or TJ 300B). It delivers full-bodied 10W output ideal for high-sensitivity speakers, praised for quiet operation, wide bandwidth, deep bass, tonal accuracy, and micro-dynamics.
