Bad Philips CRTs.

[dr.ido]

Lately I've been having a bad run of Philips A68ESF002X11 CRTs. I don't know what other sets used them, but these have all been in various Loewe sets (Profil 3272, Profil Plus 3472, Calida 5072).

I accumulated a bulk lot various Loewe sets. So far after repairing 3 I find the CRT is bad or goes bad within a short period of time. So far 2 have developed a shorted red gun (one intermittant), on the other the green gun is shorted.

Has anyone else encountered this or is it just a freaky coincidence?

It's quite frustating as I'm now less inclined to bother with the 4 sets I've yet to look at (including an Art 1 that I was looking forward to getting running).

I don't have a CRT tester so all I can do is hook a suspect CRT upto a good chassis and wait. I though I'd finally found a good one, but it only lasted a few days before the same short appeared.
