The preamp sections are based on a layout of two 12AX7's in Channel 1 and one EF86 in Channel 2. The two 12AX7's in Channel 1 create a parallel-triode circuit with interactive bass and treble. The one EF86 in Channel 2 consists of a high-gain pentode coupled to a six-position tone switch. Outright benefits include quick dial-in of new tones and an easy return to the settings you learn to prefer. Also "high treble" cut control, master volume, with a bypass feature that offers flexible control of the power amp section. The power amp is fed by a 12AX7 phase inverter, which drives four EL84 power tubes. The rectifier circuit gives you the flexibility of using one 5AR4 for a quick attack or you can use two 5V4's for a smooth round response. Other professional features include an effects loop, half power-mode switch (a conservative 30 watts switching to 15 watts), output impedance selector (4, 8, 16 ohms) and a speaker phase-reverse switch.
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.
