Bose® 901 Series I Active Equalizer #28322 Repaired

From Rain City Audio:

This Bose® 901 Series I Active Equalizer #28322 came through the shop for an overhaul. The original series, these Series I Active Equalizers have the oldest electronic components which are nearly universally out of their service lifetime and needing to be replaced.

The output capacitors in this equalizer looked like they could have been replaced at one point, but the rest was all original.
