The Fisher 400 from 1963 is the sweet spot of the golden age. Before the 500-C and the 800-C, Fisher had the 400—a 45-watt-per-channel tube receiver that packed a built-in FM multiplex decoder, four inputs, and a phono stage that still makes me question why I own separate preamps. It was Fisher’s answer to the big dogs, and it beat them on value without sacrificing soul.
Avery Fisher wasn’t playing around. The 400 uses four EL84 output tubes per channel in push-pull, with a pair of 12AX7s and a 12AU7 in the preamp. The output transformers are the real stars—those big, heavy units that Fisher sourced from Stancor or wound in-house. They’re the reason this receiver sounds so liquid, so three-dimensional. The 400 doesn’t have the punishing grip of a McIntosh 240, but it doesn’t need it. It’s a receiver that makes voices vocal and strings stringy.
What makes the 400 special is the multiplex decoder. In 1963, most receivers required an external adaptor if you wanted stereo FM. Fisher built it in. That was a big deal. It meant you could plug in a dipole antenna and get stereo broadcasts with zero fuss. The decoder is a tube-based unit, and it’s surprisingly quiet—no excessive hiss, no channel bleed. The 400 handles FM like it was made for the format, which it was.
The sound is warm but not syrupy. It has that classic tube bloom—a slight roll-off in the top octave that makes cymbals sound like cymbals, not broken glass. The bass is round and full, not tight and dry. If you want the kind of midrange that makes you forget you’re listening to a receiver, not a separate preamp and amp, this is it. The 400 makes you listen to the music, not the gear.
One honest caveat: the 400 is old. Tubes are available, but the electrolytic capacitors are fifty years past their prime. You will need a recap—at minimum the power supply and coupling caps. The output transformers almost never fail, but the rest of it is a time bomb if left original. Also, the phono stage is decent but not up to modern moving-coil standards. If you’re running a Shure M97xE or a Grado, fine. If you’ve got a Koetsu, buy a separate phono preamp.
But once it’s restored, the Fisher 400 is a piece you never sell. It’s the receiver that proves you don’t need to mortgage the house to get world-class tube sound. It outshines the Marantz 7 on everything except bragging rights, and it’s cheaper than a McIntosh C22/MC240 combo by a factor of three. The 400 is the receiver that makes you wonder why anyone spends more.
Put on a record, turn the volume knob past nine o’clock, and let the tubes warm up. That’s the sound of why we do this.
