Scott 311-A Wide-band FM Tuner
(click on drawing for detailed view)
Most H.H. Scott FM tuner designs (including those found in AM/FM models) were
closely based on the Type 311-A Wide-band Tuner design dating from 1955. The 311
introduced the 3-tube, IF/Limiter section used on
ALL Scott tube tuner designs (except the 4-tube IF-section, 310-series) and the final "Compactron"
370/LT-111 design. One typical variation (Type 314) was to substitute a
6FG6 "magic-eye" for the signal meter.
Nearly all Scott tuners used the same
"silver-plated," cascode, front-end tuning gang using the 6BS8/6BQ7A
and the 6U8.
