RDL ST-GCA1 Automatic Gain Control Audio Amplifier module NOS

Listing is for Radio Design Labs (RDL) automatic gain control amplifier (AGC), model ST-GCA1 in new never used condition. It is an earlier version for current GCA3 product and was purchases several years ago but never used. All factory enclosures are included, plus an OEM miniature power supply that is not part of the factory package but can be used to power the module. Initial idea was to package the module and the power PCB into a project box to use as a pedal.

From RDL (See more details in the attached photos, last two pictures were taken from an RDL user manual) :

" The ST-GCA series products are unique, high-performance electronic modules offering constant, automatic level control of audio lines. Both constantly adjust for changes in input levels; bringing up low levels, and reducing high levels. The ST-GCA1 is the ideal choice anywhere slowly varying audio levels such as music need to be maintained at a constant level. The slow gain-riding maintains the desired average operating levels without introducing any audible compression artifacts. Gating circuitry is used to mute the output when no input signal is present."
