Transistor video amplifier and line time-base synchronization circuits for television receivers
M.C. Gander, Peter L. Mothersole · Journal of the British Institution of Radio Engineers · 1962
The principles of circuit design for transistor video amplifiers for use in television receivers are illustrated by a design using a transistor type AF117 as an emitter-follower driving an AF118 video output stage.The problems arising from the use of transistors in the synchronizing and line oscillator circuits are discussed. Complete synchronizing pulse separator, flywheel and line-drive circuits are described for both 405- and 625-line receivers. Some alternative circuit techniques are also considered.
