Fisher 50-A
Not much information survives on the Fisher 50-A. The model name shows up only in period advertising from early 1954, where it was listed as a 50-watt amplifier next to Fisher's FM-AM tuners. Fisher's own ads in High Fidelity (March 1954) called it a "50-watt amplifier" with "100-watts peak!" and claimed it was the "world's finest all-triode amplifier." The same ad copy ran in the May 1954 issue of High Fidelity, paired with the Model 70-RT tuner. Past these brief promotional mentions, the Archive's sources have no schematic, no service manual and no independent review of the 50-A.
What little can be said with confidence:
- Rated output: 50 watts continuous, 100 watts peak (manufacturer claim)
- Circuit type: all-triode (per period advertising)
- Advertised alongside Fisher tuners in 1954, suggesting it was a component in the company’s early high-fidelity product line
No production years, original price, dimensions or detailed technical specs are documented. The 50-A appears to have been a short-lived model, overshadowed in the collector world by Fisher's later integrated amplifiers and receivers.
