Info
The 135 was a completely passive device, that provided central control of two mono amplifiers.

Controls included:  AC power switching, Master Volume, Loudness compensation, stereo/mono function selector. 

Introduced the very narrow "H" case/chassis, later used on the 335 MPX Adaptor.

The 135 was an innovative and inexpensive "stop-gap" solution that introduced the then-new (1957) concept of two-channel LP stereo phono sources.

It permitted Scott's installed base of monophonic users to protect their investment, while Scott engineers worked on integrated Stereomaster designs like the 130 and 299.
