ELECTRONIC TECHNICIAN/DEALER JANUARY 1971 TEKLAB REPORT The familiar "link circuit" has now been replaced and the color -difference and luminance signals are matrixed before they are fed to the CRT Introducing RCA's Argosy Portable Color -TV Set by Joseph Zauhar The Argosy portable color -TV include active side -pincushion cor- set, with its CTC49 chassis, takes a rection, transformerless vertical out- large step into the future with a num- put, matrixing of the color -difference ber of radical changes.

After the back cover is removed the complete chassis is exposed for servicing, the modules can be re- moved from their edge contacts by lifting two retaining clips. The main chassis mounts the power transform- er, power -supply filters, audio -out- put transistor, two vertical -output transistors, high -voltage quadrupler, focus bleeder, and the SCR's and di- odes of the horizontal -deflection sys- tem. Some of the circuitry has a close resemblance to earlier RCA chassis -such as the tuner, AFT and hori-
