The preamp section is based on a layout of two 12AX7's and one EF86. Channel 1 is a parallel-triode circuit with interactive bass and treble, similar to the C-30, but with a wider range of tone control. Channel 2 consists of a high-gain pentode coupled to a six position tone switch. A "high treble" cut control in conjunction with the master volume with a push/pull bypass feature offers flexible control over the entire power amp section. The power amp is fed by a 12AX7 phase inverter which drives two EL34 power tubes which gives the amp punch and sensitive touch response. The rectifier circuit is driven by one 5AR4 for quick attack. Other professional features include an effects loop, output impedance selector (4, 8, 16 ohms), a speaker phase-reverse switch and two courtesy AC receptacles. Logo and indicator lights glow red.
Class A refers to a high performance style of circuitry used in vacuum tube audio devices to extract maximum efficiency from power tubes. A constant high voltage signal is sent through the power stage without the forced negative feedback (or "cool down cycle") inherent in the Class A/B design. Matchless amplifiers rely on superior design, construction and components to manage the power of true Class A operation. Matchless Class A amplifiers provide an "alive" response, true tone, rich harmonics and smooth transition into distortion.
If you are looking for circuit boards in a Matchless amplifier, you won't find them. Matchless amplifiers are point-to-point wired, using military-spec components and hand wound transformers, without circuit boards of any kind. While these construction methods are more difficult and expensive than others, they are necessary to achieve the incomparable sound quality, reliability and ruggedness of a MATCHLESS.
