Historical Significance
The Fisher 800-C was released during the golden era of vacuum tube audio equipment. It was designed to give reference-grade performance in both amplification and radio reception, which made it one of the first high-end integrated receivers. Fisher, founded by Avery Fisher, was known for uncompromising quality, and the 800-C followed that philosophy.
The FM tuner section was very sensitive and stable, and it rivaled standalone tuners of the time. The multiplex stereo decoder let it reproduce the new FM stereo broadcasts with clarity and spatial accuracy. It used premium components, such as custom-wound transformers and a high-quality tube complement, and that set it apart from competitors.
The 800-C was one of the last great tube-based receivers before solid-state took over. It is often cited as one of the finest tube receivers ever made.
Sound Signature
The Fisher 800-C has a warm, rich, highly musical sound. Its sound is characterized by:
- Smooth, extended highs without harshness
- Lush midrange with excellent vocal presence
- Full, controlled bass that remains articulate
- Excellent stereo imaging and soundstage depth
Often described as "tube lush," the 800-C adds a pleasing harmonic richness that suits acoustic, jazz and vocal recordings. Its built-in reverb adds a subtle ambience, particularly with older recordings.
Maintenance and Restoration Tips
Because of its age, most Fisher 800-C units need restoration to run safely and reliably. Key considerations include:
- Capacitor Replacement: All electrolytic and coupling capacitors should be replaced. Old capacitors can leak, cause distortion, or damage other components.
- Tube Replacement: While original tubes may still function, testing and replacing weak or noisy tubes (especially the 7591s and GZ34) is recommended. Use matched pairs for optimal performance.
- Resistor Check: Carbon composition resistors can drift out of specification over time. Critical resistors in the signal path and power supply should be tested and replaced if necessary.
- Cleaning Controls: Use contact cleaner on volume, tone, and input selector pots to eliminate crackling and noise.
- Power Transformer: Inspect for signs of overheating or hum. Avoid prolonged operation at full power until the unit is fully serviced.
- Bias Adjustment: The 7591 output tubes require proper biasing after installation. Ensure bias is checked and adjusted during restoration.
Have the unit serviced by a technician experienced with vintage tube gear. Proper restoration keeps it safe and brings out the full sound of the 800-C.
Collectibility and Market Value
The Fisher 800-C ranks 9/10 in collectibility because of its legendary status, limited production run and lasting reputation. Fully restored units in excellent cosmetic and functional condition command premium prices.
- Market Value: $800 – $2,500
(Varies based on condition, originality, and quality of restoration)
Original packaging, manuals and documentation can raise the value further. Units with all-original tubes and low usage are especially rare and desirable.
Conclusion
The Fisher 800-C is a vintage amplifier, tuner and decoder in one box, with powerful amplification, strong tuner performance and a luxurious sound. It has held the interest of audiophiles for over 60 years after its introduction.
