Hermon Hosmer Scott first built
high-fidelity pre-amplifiers with the patented Dynaural Noise Supressor (the Dolby Noise Reduction
System of its day) for the commercial broadcast industry. Early on, H.H.
Scott sold (under license) DNS circuits to the then prestigious, E.H.
Scott Radio Co., of Chicago, IL. After World War II, H.H. Scott
found an emerging consumer market eager to acquire his own amplifiers and began offering them
in 1947, from facilities at 385 Putnam Avenue, in Cambridge, Mass.
In 1952, H.H. Scott introduced the first "slim-line" integrated amplifier,
99-A.* This unit featured an innovative design. The packaging consisted of
"laid-back," output tubes mounted at a "canted" angle. This permitted
the affordable Type 99 (being a completely enclosed integrated
amplifier: i.e., combining preamplifier, equalizer, 10-watt power amplifier and power
supply), to find popular acceptance in the living rooms and dens across
Prior to the introduction of the H.H. Scott Type 99, most consumers would not accept
the complexities and drawbacks of early Hi-Fi products. Consumers and home decorators
simply did not embrace hot, exposed vacuum tubes and transformers in their living rooms!
The innovative H.H. Scott Type 99 packaging set a styling standard for consumer audio
components that the rest of the industry follows to this very day. This
packaging format (known as the "C" case) was commonly found on other
H. H. Scott products in the mid-fifties through mid-sixties, including the
Type 210-E/F integrated (mono) DNS-amplifier and the Type 330 AM/FM wide-band
In 1958, Scott introduced its revolutionary "Stereomaster" family
with the TYPE
299 integrated amplifier. The stereo LP-record (1957), reel-to-reel 4-track
stereo tapes, AM/FM stereo "simul-casting" and later true stereo
(multiplex) FM broadcasting (1961) were increasing the demand for Hi-Fi products. The
talented Scott engineers performed their "magic" again. And the then
(in late 1957), H.H. Scott manufacturing facility, (located on Powder Mill
Road, in Maynard, Mass.), helped
supply the ever-growing demand for Scott products.
The Type 299-family was even more popular than the Type 99-family, and for many of the
same reasons: economical cost, easy-on-the-eye styling, compact packaging (using the
then-new, miniature, "baby-with-bite," EL84 -- 6BQ5 -- 7189 tube family),
and most importantly -- excellent sound, all combined with the famous H.H. Scott reputation for
"rock-solid" reliability. In fact, it is safe
to claim, that the Scott "Stereomaster" Type 299 (and its siblings)
became the most successful, mass produced integrated vacuum tube amplifier,
Modern-day vacuum tube enthusiasts collect and appreciate Scott amplifiers for many of
these same reasons.
* Editor's Note: The Type 99 was one of the few products that did not adhere to the H.H.
Scott product numbering system. (Apparently the Scott marketing department wanted to hype
the original price of "only" $99!) The Type 299 was introduced at $199, yet used
the traditional product numbering system.
