Untested – no power-on or signal testing performed. Vintage Stromberg-Carlson AR-37 tube amplifier paired with a Fisher preamp/equalizer. Both units are from the late-1940s to early-1950s era and were part of an early hi-fi/record-reproduction setup. The AR-37 is known for its 10-watt output, five-tube design, and built-in equalization network intended for pre-RIAA record curves. The Fisher preamp adds tone shaping and gain control typical of early Fisher engineering. Both units are untested. No power-on or functional checks were performed. They are offered AS-IS for parts, restoration, or display. Five-tube amplifier (6SN7GT, 6SN7GT, 6F6, 6F6, 5Y3GT). Rated around 10 watts output. Bass boost, treble attenuation, and compensation controls. Metal chassis design typical of late-40s Stromberg-Carlson engineering. Cosmetics show age-appropriate wear. No guarantee of completeness or functionality. No cables or accessories included. AI has added the following description after all the photos were loaded. ? Identification of Your Components. A Stromberg-Carlson chassis with a 50-60 cycle, 105-125V plate. A large power transformer and multiple octal tubes. A front panel with Fidelity / Treble / Bass / Volume controls. Serial numbers consistent with late 1940s-early 1950s SC sound equipment. This is not an AR-37. It appears to be a higher-power Stromberg-Carlson PA/Hi-Fi amp, likely in the 20-30 watt class, closer to models like the AMP-1, AMP-2, or AMP-24 family. These sell higher than AR-37 units because they have more output and better transformers. Early Fisher bird logo. Markings for AES, NARTB, LP, 800, etc. This is an early Fisher phono preamp/EQ, late 1940s-early 1950s. These are collectible because they predate the Fisher hi-fi receivers of the 1950s-60s. The wooden case with a handle and combined front panel is a period custom build. These were often used in. Collectors like these because they show real-world use and originality.
