Here is a really cool Fisher Master Audio Control 50c mono preamp from the 1950s. It has been in my friend's dad's basement for some time. I have a Fisher 500C that I was planning on pairing this with but then three of my old guitar tube amps took dumps on me and I blew my repair budget on those. So now it is up for sale! I haven't plugged it in and have zero idea what it's operating condition is. The unit looks clean enough. The wood enclosure isn't perfect. It is missing one slider knob, which are available on ebay. The brass faceplate has plenty of patina.

Fisher is an American hi-fi name founded in 1945 in New York by Avery Fisher. In the vacuum-tube and early stereo era, The Fisher Radio Corporation built a strong reputation for carefully engineered, high-quality home audio gear and helped define what “hi-fi” meant to serious listeners in the 1950s and 1960s.
Historically, Fisher’s core products were amplifiers, receivers, tuners, and other home audio electronics rather than modern lifestyle categories like headphones, DACs, or cables. The brand was especially associated with tube amplifiers and stereo receivers, along with related components that brought higher-fidelity sound into mainstream living rooms.
Today, Fisher is best understood as a vintage-collector and heritage hi-fi brand rather than a current high-end market leader. Its classic equipment is respected among enthusiasts for its sound quality, build, and historical importance, while the brand itself has long since moved away from its original position as a premium American audio manufacturer.
