Years ago I ‘lunchboxed’ one of those above-depicted RCA BE100 equalizer modules. The RCA 100 series of the early 70s was the end-of-the-line for RCA’s pro audio gear. The series consisted of the MI-141651 op amp, the BMM-100 Mixer (channel strip, aka MI-141550), BE-100 EQ (aka MI0141560), BA-101 and BA-103 preamps (also designated as MI-141501, MI-141503), BMM-110 Submaster module (aka MI-141570), and BIM-100 Isomix amplifier (aka MI-141520).
Since I seem to be one of the few fools who has publicly admitted to spending time messing around with these things, I’ve gotten several requests over the years for the accompanying data and schematics. Well guess what. TIME HAS COME TODAY. Download all of the tech date for all of these modules.

Do you know where I could find a schematic for an RCA ba-17 “record amp” ?
One knob mic pre that came racked with a cart recorder…
Always love your stuff!
@Andrew – I don’t have one for the BA number, but do you have an MI number for that?
BA / RT 17A MI-11966-A and MI-11965-A
funny that you commented mike, i’m was going to send it to you but wanted to do some of the legwork!
Ha! So that’s the one I saw at your place – keep searching please, as I don’t have it 🙂
Had about 24 channels of this, new and in the boxes, and a Scully 100 just before getting my job at Counterpoint with 2 Quad Eight Corranados and 2 A-80s and all the free session time I wanted. Jerry left out the part where I would be working every waking hour.
