Bose® 901 Series II #65097 Overhaul

This Bose® 901 Series II Active Equalizer, #65097, just came through the shop for an overhaul. It worked briefly, but failed quickly on its original components. Nothing that an overhaul can’t take care of!

This particular unit had its three main power supply capacitors replaced, but the rest was all original.

After all new components, upgraded output capacitors, and a thorough cleaning and testing session, this Active Equalizer works and sounds great!
