That looks like a late '80's NAP era Sylvania console. It will have the same chassis as a Magnavox or Philco. GTE started using the "superset" name on their higher end sets, beginning in the late '70's. When NAP bought Sylvania from GTE in '81, they continued to use the name. I think NAP finally phased out the superset name in the early '90's.
