Holy smokes you really scored on this one ! Best damn sets
ever made IMHO. Congrats.....
When you get inside,
Motor not stopping. On the back of the tuner there is a wheel
with tabs you twist to skip or stop each channel. on the
side of it is a rocker that works switches. The rocker sticks
so clean out the old grease & relube.
Age. Model or chassis # gives you model year. Model will
start with SC, SD or SE. S means Space Comand 2nd letter
is model year. Chassis # starts 25C***, 25D*** or 25E***
same idea. Date of mfg use 4 number date codes from major
parts. Build date is a month or two after the latest date.
Remote. Other than swapping rods nothing simple.
HV caps. This set has 5 seperate caps instead of one. They
should be changed if they havent yet. I dont think this chassis
can even cut a neck because of design of the vert output.
On newer sets the process is:
4-lead cap opens & HV goes up to 40KV +
Things start failing.
If the vert fails the yoke gets DC on it & heats up cutting
through the neck. Most of the time the HOT would short
& kill the set before the CRT went. We were a big Zenith dealer
& only did 3 or 4 CRT jobs IIRC.
