Need Part for Zenith Chromacolor-2

[robert1]

I am in dire need of a 212-149 HV Trippler for a Zenith Chromacolor 2 that is the set my wife mainly watches. the trippler (which was original) finally failed after 39 years of use. the chassis is a 25JC49 & uses a oddball trippler, the ECG 526 or 528 will not work because of this trippler has a extra connection marked as "refference".

does anyone here know of a resource as where i can find one? prefferably a N.O.S.
thanks.
please pm me if you may have info on one.

There was a lot on e-bay of OEM Zenith triplers including
many odd ball ones for EFL jugs & others that rarely failed.
That was abt a month ago, dont know if it sold, I posted
the link here cause it was a great deal. I dont remember the
-149 difference from the common -141-** but ref is usually
the low ( almost ground) end. If you wish PM me Monday &
I will look up the EC & JC chassii to see what the difference
is providing I got both manuals.
BTW if its an EFT jug there will be a plug on it with two focus
wires. EFL's started in H line on top-o-line 17 & 19 sets.

I appreciate that. this trippler does not have a plug for the focus circuit..that was on later models. the trippler looks just like a standard 121-142 Zenith trippler except for the extra connection. the connection has something to do with blanking (or something like that) because without the connection, there is no raster. years ago, i worked on a Zenith with this same chassis & tried a ECG 526 which was the direct replacement for a 121-142, & it did not work.

FYI---it crosses to an ECG 561.

I MAY have a 561 in my garage NOS, will have to check this week. I have a couple of boxes of NOS triplers and at least 2 quads too.

I appreciate it if you check. if you have one (or more), i would like to get them from you. this set is my daily driver & my wife is on my back about getting it fixed. i want to keep this set going for at least as long as i live (which is possible) if i can get parts for it.

thanks.

They did sell, only one bid. I might have tried for them myself had the shipping not been so high. Not that I'm a cheapskate, it was just out of my range at the time.

The added wire on the JC chassis is marked grey-brown.
Goes through a 100 ohm to GND. Also goes through 1.1 meg
to low end of the G-2 controls.
No subs listed at that time.

Thanks!, i knew that this was a oddball trippler that only worked on that particular chassis.

[robert1]

i just checked moyers electronics & they do not have one. they sold the last one they had last week :-(

I hope this is not the set like one I worked on years ago that has always stuck in my mind. We had a Chromacolor 2 that would destroy a new tripler on turn on. It took us a few trys and we finally tried a new flyback and tripler together. When the tripler was disconnected the flyback would act normal. Once connected the tripler would short immediatly. If I can find the schematic I'll let you know.

[Zenith26kc20]

Found the service manual. There are no notes about tripler/flyback failure. The reference line shows a 7 watt resistor going to brightness limiting from the tripler. This must supply a voltage to the video circuit to allow it to control brighness. The only note is about stretched vertical. A zener in the power supply fails and causes that.

Zenith replaced your 212-149 tripler with a 977-45 kit. Go with the original - no other way to ensure it will work.

None on ebay, Moyers never did the Zenith thing. Give George at talonix a try.

Cheers,

Thanks!, i sent them a request on their online contact form. i hope that they reply. there is no phone number listed on the site.

In my case, the trippler failed with the usual failure... insulation breakdown. it started with a slight HV leak (hissing) for about a month before the all of a sudden failure. it is amazing that it has lasted this long, this particular failure was a big issue with these sets as far back as the 80's.

damn.. I have a TON of Zenith CC2 parts, but not that tripler.
The only triplers I came up with ( if anyone is in need)
are:
212Z9529
977-00036 Tripler kit ( tripler is a 212-141-05)
212-130
Also found an OLD Zenith flyback. Can't tell if it's for color or B&W. Part number is :
S-68398
