Representing a new direction for Fuchs Audio Technology, the Blackjack 21™ brings the high build quality and awesome tones people expect from Fuchs products to a new more affordable price range. The Blackjack 21™ is based on a dual 12AX7 preamp stage and a push-pull dual 6V6 fixed bias output stage. Unlike other amps in this price range, the Blackjack 21™ has a full compliment of extremely flexible tone controls. A liberal amount of clean headroom is available before the output stage begins distorting with a sweet yet cutting rock edge. Voiced like its siblings the Train 45™ and Lucky 7™, the Blackjack 21™ has a classic rock voice similar to a vintage Marshall or Trainwreck™ style amp, but with a more manageable power level. Its tone provides a cutting rock edge, filled with harmonic richness and chime. The circuit design also is “attenuator friendly”. (*) The Lucky 7™ and its higher powered sibling the Blackjack 21™ have a preamp stage designed to allow clean-to-mean from the guitar volume control. The chassis (like all Fuchs products) is aircraft grade aluminum, our internal construction is mixed PC board and hard wired. On the Lucky 7™ and Blackjack 21™, the preamp tubes and power supply circuitry are on the circuit card, while the power tubes and transformers are mounted directly on the chassis. A detachable power cord is standard. By using single point grounding, the amp is quiet and free of hum at all operating levels. A single input and single ¼” output jack are provided. Features: ¾” solid wood cabinet with durable tolex covering. Anodized aluminum chassis with long-lasting silk screened labeling. Heavy duty Cliff brand jacks. Solid metal shaft Alpha potentiometers. Ultra-long-life neon pilot lamp and heavy duty AC power switch. Simple user adjustable fixed bias. Specifications: Size: 8” tall 10.5 inches deep 19” wide. Weight 12-lbs. Tube compliment: 2 X 12AX7 preamp tubes, 2 X 6V6 power tubes. Power output: 21 watts into 4 or 8 ohms. Input Impedance: 1 Meg. Output impedance 8 Ohms.
