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-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.

This preamplifier has already won the reputation of being the best stereo control center available. HI FI & MUSIC REVIEW magazine reports that the 130 "has so much flexibility that it defies adequate editorial treatment. " This unit bas separate Bass and Treble controls on each channel for accurate speaker balancing.

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.

American manufacturing
Mono Integrated Amplifier, 30w
7 tubes: 12AX7(3)-12AU7-EL34 or 6CA7(2)-5U4GA.

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.
