Popular Electronics JUNE 1980 THE new 1980-81 XL -100 color-TV chassis introduced only recently by RCA's Consumer Products Division em- phasizes new technology, reduced parts count, and lower power consumption. New technology includes SAW (surface acoustic wave) filters and more sophisti- cated ICs, including one that processes most luminance and chroma functions. A few discrete transistors are used in these chassis, mainly in the power sup- ply, sweep circuits, and final picture - tube drivers. The entire circuit assembly fits on a single "planar" printed -circuit board that measures 121 sq in. Three chassis are included in this to- tally new line of moderately priced. color receivers-13" CTC 107, 17" and 19" CTC 108, and 25" CTC 109. The only notable difference among the three is a few extra turns on the flyback trans Popular Electronics Tests NewRCA XIiOO Col rTVCIrnssнs former of the CTC 109 console series to obtain additionally high voltage for the larger picture tube.
