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.
