The Fisher was the brand name for hi-fi electronic equipment manufactured in New York by The Fisher Radio Corp. during the "golden age" of the vacuum tube, which was named after the company founder, Avery Fisher.[1][2][3]
During this period, similar brands were H.H. Scott, Marantz, Harman Kardon, and McIntosh. Some of the early 1960s models were also available as kits. Fisher tube equipment is considered quite collectible today.
Fisher's first receiver was the model 500, a mono AM/FM receiver using two EL37 output tubes. It had a brass plated face panel and an optional mahogany or "blonde" wooden case. This early mono receiver should not be confused with the later stereo tube receiver models, the 500B and 500C.[1] These later receivers made in the early 1960s were stereo using push-pull 7591 output tubes. They were also sold with optional wood cabinets and had aluminum faceplates instead of the brass on the earlier 500 receiver.
Well-known models include (but are not limited to):
The Fisher was also used on Fisher's early US made solid-state equipment, such as the model 210 receiver.
Fisher FM tuners and receivers often used similar designs and components thus allowing parts to be swapped between various models. A good example is the FM stereo multiplex decoder module.[1]
