For sale, we have a Audio Control Model C-22 Octave Equalizer in Minty physical and working condition. The unit is from the original owner, and while it had not been used for a number of years, it was kept inside the owners house in a wall unit. We cleaned all the controls and switches, and then treated them with Deoxit.
We don't have the original box for this unit, but we take packaging and shipping seriously. We spare no expense and use heavy duty boxes, several inches of polyethylene foam on all sides of the unit, and use water activated, fiber reinforced tape on all seams.
