Could this be an early IC?
I see 3 caps, a transistor, a diode, 2 resistors, and a coil, all in a package mounted on a octal base. I haven't traced out the circuit yet.
OK, I know it's not an IC by the defination we use now, but it is a complete
circuit in an enclosed plug in package.
It was made in the RCA R&D lab at Canden NJ in the mid to late 50s.
