Hi,
I have all the service manuals and docs from a main east coast EV service center from the 70's, and nothing in my doc shows this AMP.
Size wise it seems like the 1144 or 1244 amp, but all the amps I see, (not including receivers) have at least 3 functions (Tuner, Aux, Phono) where this only has 2.
The look of the front, and back panel appear to be very similat to the EV-1180 receiver. Does the amp board use old TO3 pnp Germaniums?
I wonder if this was an EV amp used in an EV Record Player.
