Probably an early-to-mid '70s piece designed for RCA by Moseley Electronics. Some of you ol' engineers may remember working with (or on) one of these. This one has seen some modifications, to be sure.
The black lacquer-style finish is in very good appearance for age. No power cord, sorry: it's that curved two-lead type that uses a small round housing. I unfortunately do not have any that fit.
That upper AFC section appears to have been cobbled together using a panel blank, rather than the original RCA plug-in module. That slot is normally where the FM exciter is found. There's no RF output on this machine. The two sections on the bottom are blank/empty. There is a mono input adapter in the middle slot, part MI-560716.
I have another, working BTE on 97.5 currently for sale (as of 4/2/16) - buy both and put together one really good unit!
About 19 x 14 x 10.5" (7 RU) high, including projections on rear; weighs about 37.5 lb.
Please note this is old electronics and as such is sold as-is. I have described this item to the best of my ability and do not intend to misrepresent.
Note a return policy is available. If it's not what you were expecting simply ship back to me for a refund.
