Magnavox 32" Set Question?

[dewickt]

I have been nursing a 1991 Philips (on 24/7) with a GR1CX chassis since it was new, chassis is still perfect but I am on my third CRT. First one was a NEC 31V it faded with no emission, second was a Philips 32V made in Germany, it lasted over 10 years till first the blue then green guns lost emission, even shot the tube with the Sencore but the cathodes were to far gone. The third tube is a Phillips out of the Ohio Ottowa plant, 3 years and still looking good. The Philips LG tubes were a cheep cost effective tube but not long life.
