I just finished a new project over at Rain City Audio – Bose Active Equalizer Model 800 #003833 Repair

Those Bose Active Equalizer model 800 is from the early run of the Bose 800 PA system, which is very similar to the Bose 901 direct/reflecting speaker system. The equalizer had bad noise and distortion in both channels when I got it, but after a repair works and sounds perfect and will last for a long time to come.
