Price is stupid but this is the first consumer TV / monitor from Zenith.
Model SN1975P
9-160 system 3 chassis with beefier audio & on off timer.
If you ever get one watch out for the vol knob, they snap off easy.
When it was a year old model the dist found 24 of them in a corner.
I bought them all for a song & the boss was pissed.
Got free freight & 90 days free floor planning. Sold them all in 3 mos
& made a cool $150 on each, double the usual profit on a 19".
Oh those were the days !

The N set is super rare, ( but not valuable) almost anyone would get the remote model.
the SY set is probably a carry over. Odds are only the model ## changed.
Big chassis change coming that fall.
CRT reliability very high. I still have a perfect 13" from 1980.
Chassis is high. Most problems are known & easy. They sold millions of the chassis over 4 years so lots of parts out there. 100% modular too !
