GE Portacolor Chassis AB-E

I remember a BC chassis that was used in some 13" and 17" sets; but, I don't consider this a real GE chassis. I think the tuner and control assembly might have been from GE; but, the main chassis board was sourced from Matsushita. Every one that I saw had a bad flyback and they usually went out with a loud BANG and a big puff of smoke. Towards the end, there was another 25" chassis that was sourced from Matsushita and it also was a flyback eater (TLF14423F was the part number for the flyback, IIRC). Then, there was the 19" MK-II chassis that was sourced from Panasonic. The biggest problem I remember with that one was an orange disc cap in the horizontal output stage that would short and burn, often taking the HOT and regulator with it. I've also seen some later GE B&W's that were rebadged Samsung and some small screen color TV's that were rebadged Goldstar. Concerning the real GE B&W's, I remember the S series tube chassis, the XA solid state chassis that was used in 19" and 22" sets, and the XB chassis that was used in 12" and 15" sets. In fact, I still have a 12" and 15" set, both using the XB chassis.
