I finished recapping my Zenith tonight and was ready to test it out with the new CRT, but I now have reason to suspect that the rebuilt CRT I bought awhile back isn't really a 17LP4. While it does look nearly identical to the original, I'm having problems getting it to fit in the cabinet properly. I've managed to get it inside, but it looks "different" once you get it in there. I can see the edge of the black frame that supports the CRT more than before, and it looks higher up with more of a gap at the bottom. Worse still, is the fact that the shafts of the switches don't stick out as far as before, and I can't even get my power/volume knob on far enough to keep it in place.
I don't know what to do, honestly. I've been working on this all night, and I'm exhausted. I've pulled that chassis out 3 times so far, and I still can't get it right. Guess I'll try and figure it out tomorrow...
