I have a Zenith set that looks almost identical to that one. But the model number on mine is missing. I haven't been able to get the vertical sync circuit to behave correctly with a proper repair (but I kludged something to get it to lock). Problem looks to be one of those 3 legged disk with cryptic Zenith part numbers stamped on them. Anyone have a diagram of the typical vertical circuit they used in these sets? Or information of what's supposed to be inside the 3 legged disks? TIA
One difference I see is the location of the volume control knob.
