Fisher Coronet II (C-55) (1959–1960)
At 12 watts per channel, it won't shake walls - but in 1959, that gold-anodized faceplate promised a new era of living-room stereo.
Overview
The Fisher Coronet II (C-55) was one of the earliest integrated stereo receivers to bring stereo hi-fi into the American home. Fisher introduced it in 1959, right when broadcasters and record labels were just starting to take dual-channel audio seriously. Fisher already had a reputation for solid engineering under founder Avery Fisher. The company pitched the C-55 as a complete audio package, with an AM/FM tuner, preamplifier, and power amplifier on a single chassis. The 12 watts per channel looks modest next to later gear, but it was enough to drive the efficient speakers common in late-1950s systems. Selectable impedance taps handle 4, 8, or 16 ohm loads. The look is pure mid-century. A broad gold-anodized aluminum front panel anchors the layout, and a precision slide-rule tuning dial dominates it. The dial worked, and it also showed off.
Key Features
Gold-Anodized Aluminum Front Panel
The gold-anodized finish on the C-55 faceplate is a hallmark of Fisher's design language from the period. It resists tarnishing and gives the tuning scale and control labels a high-contrast backdrop, which helps legibility. The material also reflects Fisher's emphasis on durability and premium presentation. Competitors used painted or plated steel.
Slide-Rule Tuning Dial
The slide-rule dial was the selling point of the C-55. It allows fine station selection across both AM and FM bands. A rotary dial can overshoot, but the linear scale gives you a visual reference, which suited users who wanted exact frequency placement. That mattered for FM stereo multiplex broadcasts, which required stable tuning to maintain channel separation.
Integrated AM/FM Tuner with Stereo Multiplex Capability
In 1959, stereo FM broadcasting was still in its infancy, and few receivers could decode it. The C-55 was among the first to include an AM/FM tuner capable of receiving stereo multiplex signals, which made it a forward-looking choice for early adopters. The fact sheet does not specify IF stages or sensitivity. The multiplex decoding alone put it at the cutting edge of consumer tuners at the time.
Separate Bass and Treble Tone Controls
The built-in preamplifier has independent bass and treble controls, so users could adjust the sound to the room or the speakers. Integrated receivers of the era did not all offer this, and Fisher included it on the C-55.
Stereo Headphone Jack
A stereo headphone jack on the front panel was an advanced feature in 1959. It allowed private listening without losing channel separation, which suited late-night listening or critical monitoring.
Phono, Auxiliary, and External Tape Inputs
The C-55 has dedicated inputs for phono (moving magnet), auxiliary, tuner, and tape. The tape loop requires external patching. The input selection made it adaptable to the changing home audio setup, where reel-to-reel tape recorders were gaining popularity among enthusiasts.
Historical Context
Fisher produced the Fisher Coronet II (C-55) from 1959 to 1960, a narrow window right at the start of the stereo shift. It was one of Fisher's first integrated stereo receivers, arriving just as the industry moved from mono to stereo broadcasting and recording. Its ability to decode FM stereo multiplex signals gave owners access to stereo years before it became standard. The design and feature set reflect Fisher's strategy of combining laboratory-grade engineering with consumer-friendly integration, a philosophy that would define its reputation throughout the 1960s.
Collectibility & Value
The C-55 holds a collectibility rating of 7 out of 10 among vintage audio enthusiasts, valued for its historical significance, elegant design, and role as an early stereo pioneer. Units in original, working condition command the highest prices, especially those with matching serial numbers and unmodified circuitry. The current market value ranges from $150 to $300. Restored examples with recapped power supplies and tested tubes typically sell at the upper end. Non-working or heavily modified units may fall below that range. Owners report that the warm, rich sound typical of tube-based amplifiers from the late 1950s remains a draw, with smooth midrange and detailed highs. The 12-watt output limits its use with inefficient speakers, and it performs best with high-sensitivity loads. Maintenance is critical. Aging capacitors and drifted carbon composition resistors are common failure points, and a full recapping is strongly advised before powering up a long-dormant unit. Tube replacement (with types such as 6SN7 or 6V6, based on typical Fisher complements of the era) and cleaning of potentiometers and switches are also routine. Technicians note that the tuner section may require alignment for optimal reception. First-time power-up should be done with a variac or isolation transformer to prevent damage.
