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. 73 Zeno
