Rechecked the CRT and it's still fine.

Possibly the Tripler was what took this set out of service originally, I don't think that inch long crack happened instantly.
The intermittent connection may have come later, maybe when I fixed that it brought the HV up enough for the Tripler to start leaking again?

Will a 212-148-01 Tripler replace a 212 141 05? Turns out he one I have is totally wrong for this model so I will have to find another one.
The final number for all 17" + Zenith uprights with delta tubes
is 921-500. In theory you can use any tripler from an upright
to replace it. Beware of other triplers, some are quadruplers
or have different internals, pinout etc.
You got the right caps, there are 2 more on the flyback IIRC
The OEM orange ones are still around NOS. Check that 1.5 ohm
while you got the chassis tilted back, replace it with a film or carbon not a
wire wound..........
