With the CRT that I used the heat gun on, I did first put it face-down on a blanket in my back yard for a while (on a sunny summer day), then I also left it face-up in the metal can in the sun for a short while before I started the heat-gun process. If a person is going to use the heat-gun method, it probably is better for the CRT if its whole envelope is warm, not just the face.

On my CRT, the curve of the safety glass was a bit shallower than the curve of the CRT's face itself, so the foam tape around the edge held the glass away from the CRT slightly, even in the center.

Guys, thanks for the information. This is my first roundie and inexperienced in repair. The caterract is not to bad, but just seeing it bothers me and considering the condition of the set, I want to fix it.





Hope to find a CTC-5 next.

Very very nice, a cabinet style never seen in these parts.

A difference I noticed between a CTC15 and a CTC12 is that the CTC12 has VHF fine tuning as a pull-to-adjust concentric knob behind the on-off volume (the 12's power-volume is same as the brightness/tint/color knobs), at least my '12 has it this way.

That's a really nice Oriental style cabinet, it really shines! A great set to hang on to!

I generally don't go for black furniture, but that cabinet is gorgeous.
