ADR Compex 760X-RS - the John Bonham drum compressor!

The Audio Design Recording (ADR) Compex F760X-RS is a 2U stereo dynamics processor with compression, limiting, and expansion/gating. Electronics are all discrete, and the gain reduction element is a single FET which takes control signal from the compressor, limiter, and expander simultaneously. Input and output gain are set with stereo controls.

This box was widely used in the 1970s, most notably on the drums for Led Zeppelin's "When The Levee Breaks" 
 
These are very rare and this one has Jensen input transformers, and Sowter on the outputs.  Has been recapped, and is in working condition.  From a working studio.
