If it has tuners almost always a consumer set. Big exception is early
Sonys. Jacks started to show up on small sets first for use with
VCR's & cam-corders.
Almost all later 5" sets were built by Gold Star or Emerson/Orion.
They were built to a low price so no where near the quality of the
big Jap 5". Flip side to that is they became very common. Older
5" like yours were very high priced so rare.
A very nice set
