6 tubes: 12AX7 (3), 6L6GB (2), 5U4GA.

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-Daptor 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.

SCOTT 135 (1957-1960)

American manufacturing

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.

The 30 watt output stage of this complete amplifier makes it ideal for less-efficient speaker systems or where the absolute optimum in performance is 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.
