I have 14a9c50 since late 70s.
I learned color TV repair on it and keep it around.
How is your project going?
I have changed all electrolytic over the years and picture tube.
A transistor in IF and UHF tuner diode.
Chroma Demod IC and Varistor in horiz circuit as well as boost diode
Plus the usual tubes.
About what I can remember
Needs a horiz center control but haven’t found one yet.
I have original Zenith manual if you have questions. I thinks Sams too
Haven’t turned it on recently but worked ok
If I recall the procedure for screens was kill vertical with switch in back and bring each screen up until you barely see a line. Do for all three.
