I just finished a new project over at Rain City Audio – Bose 901 Series I Early Production Equalizer #00570 Repair

This Bose® Active Equalizer is the earliest I’ve ever seen through the shop, serial #570. It’s very hand made and got a complete overhaul, including some upgrades to maximize performance. With all new parts to replace the worn out and failed originals after 46 years, it’s going to sound great for a long time to come.
