Fisher 500-TX Solid State Stereophonic AM/FM Receiver (1969–1972)

Name: Fisher 500-tx
Brand: Fisher

One of Fisher's flagship solid-state receivers. Built like a tank, with a transparent sound. High fidelity from an era when "solid-state" still felt like magic.

Overview

The Fisher 500-TX was built from mid-1969 through the summer of 1972. It is a solid-state AM/FM stereo receiver, and it was Fisher Radio Corporation's top-of-the-line model during those years, holding that spot until the 1973 lineup arrived. It is the "small brother" of the 800-T, shares much of its design, and users have described it as essentially the same unit. That's no slight. A scaled-down version of one of Fisher's most revered receivers inherits a lot of good engineering.

It puts three components in a single chassis: a wideband AM/FM stereo tuner, a preamplifier, and a power amplifier. Owners report sensitive, noise-free radio reception, excellent channel separation across all stereo sources, and a wideband audio response that sounds effortless. It sounds clean and unforced, with the "transparent" quality Fisher transistorized designs are known for.

Key Features

Auto Tune-O-Matic and Presets

The 500-TX has Fisher's Auto Tune-O-Matic system. It was a futuristic feature for its time. Owners often single out the tuner presets as "freaking neat and unique," and they offered a level of convenience and precision that stood out in the late 1960s. Dial action is smooth and the memory is reliable.

Integrated High-Fidelity Design

Fisher didn't just cram separate functions into one box. The 500-TX has a high-performance tuner, preamp, and power amp, and each section was designed to perform like a standalone component. The specs: wideband response from 20Hz to 25kHz, low distortion (just 0.5%), and a damping factor of 30, which helps keep bass tight and controlled. Turned up loud, it doesn't strain. It has ample power reserve and composure.

Build and Aesthetic

Visually, the 500-TX carries the gravitas of a premium component. It typically came housed in a simulated walnut cabinet, giving it that warm, mid-century hi-fi presence that still looks at home on a modern shelf. It’s not just about looks—the chassis is built like a tank, reflecting Fisher’s commitment to durability and quality during this era. The front panel layout is clean, functional, and reassuringly dense with controls, signaling that this is serious gear for serious listeners.

Historical Context

Fisher, founded by Avery Fisher, was a name synonymous with high-fidelity excellence throughout the 1960s and 70s. The 500-TX arrived when solid-state technology was proving it could match, and even surpass, the performance of tube gear. Fisher had built its reputation on tube amplifiers, and the 500-TX showed that the brand's engineering carried over into the transistor era.

From 1969 to 1971, the 500-TX was the top-of-the-line Fisher receiver, a status it shared with the 800-T until both were succeeded by newer models in 1973. Its position as the "small brother" of the 800-T isn't just marketing. It reflects a real engineering lineage. One owner noted it actually has more power than several other Fisher models they've owned, including the 700-T, 550-T, and even some tube-based units.

Collectibility & Value

The Fisher 500-TX remains desirable among collectors of early solid-state gear. Fisher's tube components often get more attention, but the 500-TX has its own loyal following, especially among those who appreciate its transparent sound and sturdy build. One long-term owner stated plainly: "I bought mine in 2009 and it's one of the best FISHER's I have, among both Solid state and Tube."

Market prices vary. A used and possibly modified unit was listed for $1,100 in June 2024, while another asking price was noted at $950. Condition varies widely, from "needs repair" to "very nice cosmetics" and "working when stored." A service manual is available, and parts like bulbs and filter capacitor rebuild kits have appeared on the market, with a complete restoration kit listed at $167 in 2022.
