Fisher 800-B Tube Receiver (1961)
The Fisher 800-B is a stereo tube receiver introduced in 1961. It puts a power amplifier, an FM/AM tuner and a preamplifier on one chassis. Fisher built it for listeners who wanted performance and versatility in a single box, right as the hobby was moving from mono to stereo broadcasting and recording.

Historical Context
The Fisher 800-B came out at the start of the stereo era. Record labels and broadcasters were adopting stereo in the late 1950s and early 1960s, and buyers wanted gear that could reproduce it. Fisher, founded by Avery Fisher, was already known for engineering and a commitment to high fidelity.
The 800-B was one of Fisher's top receivers. It combined an amplifier section with a sensitive tuner, built-in reverb and stereo multiplex decoding. It uses 7591 output tubes, known for clarity, power and linearity. Many of its contemporaries used the more common 6L6 or EL34 types.
As a fully integrated receiver, the 800-B followed the all-in-one approach of its era. One chassis meant fewer pieces to connect, and performance stayed high. It brought high-fidelity stereo into the living room at a level close to professional audio standards.
Sound Signature
The Fisher 800-B has a warm, smooth sound with the harmonic richness typical of well-designed tube amplifiers. Its strength is the midrange, which gives vocals and acoustic instruments natural presence and texture. Bass is firm and controlled. Highs are extended without harshness.
With its tube complement and a strong power supply, the 800-B offers excellent dynamics and soundstage depth, especially in stereo mode. The built-in reverb adds a subtle ambience, which suits jazz and orchestral recordings. Audiophiles often praise its musicality, its ability to convey emotion and timing in a way that solid-state counterparts of the era often lacked.
Maintenance and Restoration Tips
Because of its age, the Fisher 800-B typically needs servicing before it can be run reliably and safely. Here are the key points for owners and collectors:
- Capacitor Replacement: Electrolytic and paper capacitors degrade over time. Replacing all electrolytics and coupling caps is strongly recommended to prevent performance issues or damage.
- Resistor Check: Carbon composition resistors can drift in value. Check and replace any out of tolerance, especially in the power supply and amplifier stages.
- Tube Replacement: The 7591 output tubes are critical to performance. While NOS (New Old Stock) tubes are available, they are expensive. Consider using modern equivalents or tested matched pairs. Preamp tubes (12AX7, 12AT7) should be checked for noise and microphonics.
- Tuner Alignment: The FM tuner may require realignment for optimal reception. This should be done with proper equipment to preserve sensitivity and stereo separation.
- Cleaning and Inspection: Clean tube sockets, controls, and jacks with contact cleaner. Inspect for signs of overheating, corrosion, or previous repairs.
- Power Supply Safety: Ensure the power cord is replaced if original (often cracked or unsafe). Consider adding a ground lift switch for compatibility with modern grounded outlets, but only if the chassis is confirmed safe.
Always power up a restored 800-B gradually with a variac. Watch for smoke, hum or excessive current draw.
Collectibility and Market Value
The Fisher 800-B ranks 8/10 in collectibility, based on its reputation, technical sophistication and historical significance. Fully restored units in excellent condition command strong prices, especially those with original finishes and matching serial numbers.
- Unrestored, working: $800–$1,000
- Fully restored, premium condition: $1,200–$1,500
- Original, mint condition (rare): Can exceed $1,500
Collectors value the 800-B for its sound and as a piece of the golden age of hi-fi. With tuner, preamp and power amp in one unit, it anchors a vintage stereo system.
Conclusion
The Fisher 800-B remains a benchmark of early stereo receiver design, combining power, refinement and innovation from 1960s high-fidelity engineering. Restoring one is a real technical challenge.
