I'm not too concerned with test patterns right now. My main concerns are those three safety caps, the CRT socket and the tripler. When I get a raster, I'll proceed from there. I can't burn a DVD anyhow - all that computer hogwash confuses me.

Those Caps. are .0018mf @ 1.6KV.
What I've done B4 is replace all 5 caps. with one 800-616 ( .01mf @ 1.6KV ) Ed |

I haven't worked on one of those sets for probably 30 years and of all the Zeniths I have, I don't have one of that model. |

I really don't see what's so special about the 22-5001 special cap. I mean it's just a capacitor - I didn't know it was that critical. If I used a .0018 with at least a 1.6 KV rating - what difference does it make? I took the 25DC56 out of the cabinet today. I'm going to take it to the radio club and clean all the controls and whatnot. I'm also supposed to get a CRT tester.

Interesting thread. I'm glad I learned that polyester caps can't handle the high voltage pulses. Polypropylene it is. I can't wait to get this TV fixed - I already know where I'm going to put it. I'm keeping my fingers crossed that the CRT checks good. Assuming I get a tester tomorrow.

I took the tuner out of the set and used up the last of my tuner cleaner on it. Not the Tun-O-Wash - but my newer Radioshack stuff. Even being a gold tuner, it was still very tarnished.

Good news! The picture tube checked good on my new RCA WT-115A. All three guns checked right around the same.

We also replaced the white safety caps with .002 at 1600 volt Sprague Orange Drops. Everybody there seemed to think that those caps would be just fine in there. If they're not - I'll just have to take them out again.

i just aquired a flat chassis today.had high voltage with a vertical collapse.cleaned the module and controls,voila!a working set with a beautiful crt.the cabinet is a mess but the set will also require a tuner rebuilt and full restore on the cabinet.the crt delivered a fine,razor sharp pic today.it was a trade from fellow vker Os X.i couldnt make the etf today but we made some nice trades.i got a nice bugeye zenith with stand and a zenith full tuber that needs some help.all told,good day and met a really nice fellow

Nice! I always find it fascinating with both radios and TV's that the set with the cabinet in good shape will almost always have a chassis in bad shape, and a set with a very poor condition cabinet will have a chassis in good shape - usually working out of the box. I find this phenomenon to be very consistent. Take my Zenith Chromacolor for example - the cabinet is in near mint condition, but the chassis has suffered a meltdown.

Orange drop style caps were the better and later safety cap option.

Good. I was informed that even though the new caps are only 200 picofarads higher than the original, it could still affect the horizontal deflection. I guess we'll just have to wait and find out. I'll also be deleting the instant on feature.
