Sherwood S-7700

 The S-7700 FM/AM Receiver is similar to the S-8000 above but boasts  a full 80 watts music power output (each channel 40 watts music power or 36 continuous watts at 1,5 % IM distortion).

Other features found on this receiver are a Stereo Indicator Light to provide instant identification of those FM stations broadcasting stereo programs, wide-band 3-mc gated-beam FM limiter, and 1-mc balanced ratio detector which combine to create the pace-setting capture effect ratio of 2,4 dB.

The S-7700 also features outstanding AM broadcast reception with either a 15-kc wide "hi-fi" band pass or sharply selective 5-kc pass band selectable on the front panel. Also built-in ferrite AM rod antenna; no AFC circuit as on S-8000, 22 tubes plus 3 silicon rectifiers, 12 diodes. Size same as S-8000.
