This is a complete control and power center incorporating
the results of H.H. Scott's famous engineering leadership
and skill. This amplifier is ideal for those who prefer
a top-quality monophonic system now, and wish to
expand to stereo sound later. Together with the LM35
Stereo-Adaptor it also makes an excellent add-on system
to existing amplifiers. Outstanding features include
two low-level preamp inputs that enable you to use
both a phono cartridge and tape head; extensive tape
recording and monitoring facilities; and front-panel
stereo expansion switch.

adequate editorial treatment." This unit bas
separate Bass and Treble controls on each
channel for accurate speaker balancing.

Mono to Stereo Adaptator
Expand to stereo by adding the Stereo-Daptor
and a new H. H. Scott monophonic amplifier
to your present system. The Stereo-Daptor
permits control of two separate amplifiers
from a central point. A Master Volume Control
adjusts the volume levels of both channels
simultaneously. Special switching lets you
play stereo, reverse stereo, use your
stereo pickup on monaural records, or play
monaural program material through both
amplifiers at the same time. This gives
you the full power of both amplifiers.
No internal changes are required when
used with H.H. Scott amplifiers.

required. The unique Acoustic Level Control
insures perfect operation of the amplifier with
any speaker and in any room. A convenient
front-panel switch facilitates instant expansion
of the 209 to a Stereo system, together with the
135 Stereo-Daptor and a second amplifier.
Important operating features include dual magnetic
inputs; three-position scratch and rumble filters
and extremely high gain permitting use-with
any phono cartridge or tape-recorder head.
