I think Jon in Halifax had one also & took a pix of the lead dress on his.
It was untouched & still had the OEM wire ties. Its a good point though,
I have run across dress problems where the yoke wires got too close
to the CRT cathode lines & caused it. History is I had 2 of these back in the day.
In both cases the HV was worked on but the customer didnt want to pay
the extra to look into it . 30 yrs later 2 or 3 have popped up on the forum
but nobody has found out why.

The tripler in the set HAS been changed IMHO also. Zenith never
used piles of sealant like that. Dont know exactly what it is, we
bought little tubes of it p# 205-229. They also come with new
triplers.
Anyhows for now get all the numbers off the tripler in the set & we
will take it from there.

Well I opened her up and took some pics. Don't know if the tripler is original, but it does have the Zenith PN on it. Also, attached pics of the goop on the tripler and flyback leads as well as the yoke/convergence wiring. The wires were routed the way you see by me years ago in hopes of fixing an possible interference, but it was of no help.

See the pic I just attached about the wire routing.

Here is what I see. The tripler is OEM. The date code ( 7314 ) puts
it in the range of the set being born with it. It also looks very clean.
Often they discolor or swell up when stressed by HV problems.
BTW did you change the hoz out. Its not original. There is a low ohm,
1.5 ohm IIRC & a 'lytic in the base circuit. The resistor should be a carbon or another non wire wound.

Yeah, I replaced the HOT. During the scoping for the jailbars, I shorted it. I am not sure if it was the original. At the time of death, I was unable to find an OEM, so I went the NTE route. Seems to be working fine, but I have a lead on an OEM if that is a better choice.

As for the "base circuit" I'm assuming you mean the for the HOT? If so, under it is a 600K 2KV capacitor and a diode. That's it. If not the circuit you're referencing, let me know.

Okay, I don't know where to go from here. I'm assuming the tripler is okay, and so is all I've found. Guess she goes back into storage.

Thanks for the assistance.

One last chance & if it still exists it would be good for many
of us.
Back 10-15 yrs ago there was a parts distributor (IIRC) that
ran a huge database of TV, VCR, audio etc problems, mostly dogs.
You could drill down with model, chassis easily. IIRC members also posted
OEM bulletins. We subscribed to it & it paid for itself in a few weeks.
Trouble is I cant remember its name !
I am sure someone on the list also remembers it. If its still out
there it would be great to find.
