Here are a pair of vintage DuKane compressor/limiters. They use an all discrete transistor circuit path with a FET for gain control. They come stock with a (useless) noise gate, two inputs, and some controls on the rear panel. These mods remove the noise gate, move the ratio and bypass to the front, and add release time settings. Everything gets cleaned up and boards are re-capped if needed. The results? “A super smash box” according to one user!
