In 1954, H.H. Scott perfected and introduced the first
commercially successful Wide-band FM-only tuner, the original 310(A) Broadcast Monitor, a
major factor in the popular acceptance of FM radio for Hi-Fi listening pleasure.
Then, in mid-1961, H.H. Scott was ready when the FCC adopted the current standard (Zenith/GE) for
FM-Stereo multiplex transmissions. Anticipating the FCC's final decision they
were first-to-market with the Type 335 Multiplex
Adaptor. (Also, see the Type 830 FM Multiplex
Stereo Generator and Type 4310 Broadcast Monitor).
By introducing Wide-band technology to its products, Scott's
talented engineering team, led by Chief Research
Engineer, Daniel R. von Recklinghausen,
"future-proofed" their RF products with the first "useable" multiplex

Even before commercial stereo multiplex broadcasting
was approved by the FCC (in 1961), wide-band tuner design gave superior quality reception. The
earlier research on VHF FM receivers by Major
Edwin H. Armstrong (see bio by broadcast historian, Donna Hapler), inventor of FM, clearly demonstrated the
inherent advantage of wide-band circuitry. Scott tuners were so reliable they
were often used in commercial broadcast applications (See FM
Because of the subtleties of wide-band circuitry, most
manufacturers continued to produce relatively "narrow-band" tuners which give
adequate but not the best results with monophonic FM. It remained for the FCC to
eventually point out the superiority of wide-band design in receiving multiplex: The
FCC-approved (Zenith/GE) multiplex system."

If you could only choose a single vintage H.H. Scott product to
own, most agree it would probably be one of the company's sensitive, and
