NO NO NO!!!!!!!!

It does not have the words "sensor safe" ... this means that it contains acetic
which exudes out on curing and will corrode the wires. If it smells like vinegar or
other acid, don't use it!

Ok, well I'll return it then. Where would I get the "sensor safe" stuff then? Would they have it at the Auto Parts store? I'm asking because I didn't see anything like that at the hardware store, and the only other place I saw that was online and I'd prefer not to buy it online if I don't have to.

As for the 23" Zenith TV, I finally got it out of the cabinet, and looked underneath the chassis, and it appears that there are only 7 paper caps in the whole TV Chassis (2 Bumblebee caps, 1 ceramic tubular cap, and 4 brown plastic tubular caps), the rest are either Brown or Yellow Ceramic Disc Caps or Mylar "Brown Drops" and "Orange Drops".

As for the Electrolytic Can Caps, one was a single section cap for the main AC Line Filter (that one tested bad with my ESR Meter), the second was a 4 section electrolytic can that had only one section that tested bad, and the last one was also a 4 section electrolytic can cap that had 2 sections that tested bad.

So as far as the electrolytic cans go, could I get away with just unwiring the bad sections and installing a terminal strip nearby that I could install the necessary replacement caps onto and wire the leads from the dead sections of the aforementioned can caps and then just continue to use the good sections of the original can caps, or should I just replace all of the electrolytics including the ones that still tested good yet in the original cans?

I've had good luck with Permatex Red from the Advance Auto parts on picture tube bases that have seen use. Be careful, there's 2 different reds and only one is sensor safe.

OK, I think I may have seen something like that at the local Ace Hardware (which is where I picked up the stuff that apparently wasn't sensor safe) and I didn't realize what it was because I didn't know I was looking for "sensor safe" at the time (I thought I was looking for something else with a similar sounding name.)

I'm not sure a "gasket maker" product will have the best adhesive properties.
I think a little better choice is this black adhesive. I've used it on other things and it states that it can be used on wires.

Yours doesn't have sensor safe on it.

I have one tube that was done in the red several years ago that is still holding on. That tube has probably seen at least 80 hours of use with the red. It started out in my Moto 21CT2 as a replacement for the necked 21AXP, then I got a CTC5 with a good AXP and swapped the CRTs between the two, then I found another mediocre AXP and stuck it in the CTC-5 and since then the permatex RED 21FBP has been sitting waiting to go into a Packard Bell when I get to it.

I just did another 21FBP22 with the red yesterday since the last one did well.

But it doesn't say, "Sensor Safe".
