Its a first generation System 3. Only made abt 1 year in
19" + 25" top of line sets. Still has a power transformer
with the other usual System 3 boards. Never junked one,
the most reliable Zenith ever built IMHO.
Most common problem was cold joint on the hoz drive
transformer. Also a few 24V regulator transistors, not much else.
A nice find.
