Wow, I would have never expected tripplers to still be available from any manufacturer. Hopefully its not one those deals where they say its available but when they actually check the shelves, nothing is there. I had this happen numerous times with union electronics. They list as having all sorts of NOS zenith parts on their website, but when I call to ask, they say they haven't had those parts in over 15 years...So how did they get on the website then?
Hopefully the tripper works out.

Not to mention the latest craze, 3D television. I believe it is just a fad (as was quad stereo sound in the '70s) that will fade into oblivion in a very short time, and will never really catch on as did color TV or stereo television sound. One of 3D's drawbacks is that one must wear special glasses to get the full effect. Who is going to want to wear a pair of bulky glasses for three hours just to watch one movie? The 3D glasses I've seen advertised as accessories for new 3D televisions are indeed bulky, as they are battery-powered.

BTW, when I think of 3D television, I am reminded of an episode of the mid-'50s DuMont TV series "The Honeymooners", in which Ralph Kramden (played by Jackie Gleason) and his wife Alice were arguing over why they don't yet have a television set, when their neighbors the Nortons were on their second set. "I'm waiting for 3-D television, that's why!" Ralph stormed. If Gleason were alive today (he died several years ago at the age of 71), he wouldn't have to wait any longer, as 3D TV is here today.

I remember that episode quite well and got a good laugh at that line. Jackie Gleason died in 1987, so we're talking 23 years ago already...

The tripler came in today. It's funny that it came in an NTE box; but, is marked "Philips ECG" and has a date code of 0226 (I assume this means the 26th week of 2002) stamped on it. I knew that NTE bought ECG in the early 2000's; but, I figured they would have erased any ECG markings and restamped their parts as NTE. Having an '02 date code tells me that they are likely not making any more of these and are selling off what's on hand.

I also noticed that the new tripler is physically lighter than the old one and I hope that does not indicate an inferior quality part.

After installing the tripler and turning on the set, I heard two loud HV arcs. At that time, I was getting hot and had something else I had to do; so, I didn't get a chance to see where the arcing was coming from. It's very humid and I hope a simple cleaning of the HV anode (guess I should have done that to begin with) will solve the problem. I certainly hope the new tripler hasn't sprung a leak as I don't want the hassle of returning it and possibly getting another part that's just as bad.

I didn't have any RTV on hand; but, I had some HV putty and that's what I used to seal the input lead to the tripler. Also, I reattached the plastic insulator that covers the focus terminals on the tripler. It seems that most shops never bothered to replace the insulator or add any HV putty to the input lead. However, I'd like it to be put back together as close as it can be to how it was done originally.

It sounds like the anode lead on the tube was either not seated properly or dirty. This usually caused the arcing you heard. I would be real careful as the new tripler may be dead now from the arc over. Disconnect the lead from the flyback to the tripler and with an insulated stick (be careful) push it over to the input terminal and see what kind of spark appears. A thin blue anemic means tripler still good. A fat orange spark or arc means the tripler has shorted.
Also, while you are in there, there is a 50 mfd capacitor and a 15 ohm resistor near the horizontal driver transformer. Check to see if they have been replaced. The cap dries out and the resistor then goes up in value killing the horizontal output transistor. Be careful replacing them as the positive end of the electrolytic is grounded!
I see the safety cap is an orange one (newer type). This is good because the older white one often failed sawing the neck off the CRT.

I think the trouble was simply a dirty anode connector. It actually didn't seem that dirty; but, I did clean it and got some black dirt off. After letting everything dry, it came up with a picture without any loud snapping. Before I do anything else to it, I'm going to move it from the humid, un-airconditioned basement to my shop area, which is air conditioned. Besides the usual adjustments, I need to replace the neon channel indicator lamp and the power switch. The old switch still works; but, the shaft is broken off and the button won't stay on. I think I have a good switch and button that I salvaged from a junk set. I'll post pictures when I get it finished and I look forward to putting it in the house, in place of a 19" Zenith, as a daily watcher.

Either my eyes are bad or I cant find the date. What year is this TV? OK, runs fine, nice "snow" but NO audio or video (signals?), set on Ch.3 and plugged into a DVD player. Hmm? Might someone suggest where to start? The Tuner? Mine looks just about like the one below on this page.

I got big box of Zenith parts TONs of Chromacolor parts. Many modules and boards, transformers, and other goodies. If any of you need anything, give me a list with the Zenith part-numbers. Or I can send you MY list. I'll never use all of these. Just wanted some extra modules to keep my Tv....ROSS

Nice score!

Just curious here, but everyone keeps mentioning the Inline Tri Focus tubes as something bad, what was wrong with these tubes? I have a 79 System 3 SC SP set that has one and it seemed to have a good picture (before it developed a power supply issue that I need to fix)

They seemed to go weak faster than the delta gun tubes, especially the 23" and 25" models. However, they were still better than the '90's era Zenith CRT's.

sampson159 · #27 12-06-2012, 06:09 PM

i have one in my system 3 remote set from 1977.these seemed to be very dependable and produces a fine picture.as good as the delta chromacolor sets.the early zenith inlines were very good.the early sylvania inlines were the best.i still see those supersets from the early 80s for sale here in cols,ohio.the crts are all excellent

When these CC2 sets came into the shop, one thing we would automatically do is clean the tripler and the area around it inspecting it for cracks. If we found anything, it would be replaced, even if it was still working at the time.

I never had a problem with the Delta vs Inline tubes.

In the 1990's, I saw so many failed Zenith labeled tubes. I was so glad when they got too old to still be in warranty. I replaced at least 150 tubes in portables and consoles, and had to store the bad tubes until Zenith would OK the replacements.

Also, had to repair alot of chassis because of these bad tubes, too. Used to send some of them to PTS electronics in Indianapolis, until I got a repaired replacement module that had dead roaches in it.
