Equivalent to the Panasonic PV-1730. I almost bought one back in the day, but it was ahead of the MTS stereo standard so it lacks a stereo TV tuner. This has direct drive reel motors which is why it lacks most of the usual belts & idlers.
That Pay TV switch has to do with the old subscription boxes they had back in the early-mid-80s like On TV. You would set it up to the channel the descrambler box put out so the VCR would switch to it. Something like that...
