Not sure, definately a 60's solid state (rather than tubes). The record player in that is the Zenith 3g, which means it has a 3 gram tracking force, it's an alright table. That turntable was also included in the Zenith "circle of sound" setup, where it had a built-in amp in its plinth (I have one in the basement). The other thing that dates it around the 60's is the "Genuine diamond stylus" logo in the upper right, which they used around that time. I am not sure how long the turntable itself was in production, but my circle of sound version was made in july of 1968. Not sure if the amp in the console is the same as the one built-in, but it may be

, simple little push-pull transistor deal(like many amps)
That zenith promotional sheet on the turntable is pretty cool though:scratch2:.
