Hi All:
I've looked hi and low for a schematic for this module.  (RCA MI-9285)
I've got to repair a pair of them.
Would any one have one they might share?

TIA

There are at least a half dozen variations of that circuit amongst Photophone, tape machine, and foreign RCA products, tweaked to need.  Some with bridging input transformers, some with 30Ω input transformers, some with 150/600Ω.  Various EQ networks.  Rear end dang close to the BA-21.
