Fisher TX-100 (1967)
Not much is documented about the Fisher TX-100 beyond a handful of period magazine announcements. Here is what the record shows. It was Fisher's first all-solid-state master control amplifier, introduced in mid-1967 as a transistorized successor to the wildly popular tube-based X-100. High Fidelity (June 1967, p.28) reported that the TX-100 offered "higher power, lower distortion, and of course no heat" compared to its vacuum-tube predecessor. The same article gave a per-channel rating of 32.5 watts. HiFI-Stereo (May 1967, p.19) cited 65 watts music power. The discrepancy likely comes from continuous versus dynamic power measurement conventions of the era.
The TX-100 was priced at under $200, which put it forward as an affordable way into solid-state high fidelity. It carried forward the X-100's mission of bringing component-quality sound to a wider audience. No service manual, schematic, or detailed specification sheet has surfaced in the usual archives.
Known specs (from period sources):
- Power output: 32.5 W/ch continuous (per High Fidelity) or 65 W music power (per HiFi/Stereo Review)
- Original price: under $200
- Introduced: spring/summer 1967
