A cathode drive circuit couples a video drive signal from a cathode output amplifier to the cathode of a cathode ray tube along a first matched transmission line. Any signal energy not absorbed by the cathode is coupled along a second matched transmission line to a power dissipating load. The use of matched transmission lines avoids reflections in the system and eliminates attendant signal degradation. The power dissipating load can be located at any distance remote from both the cathode output amplifier and the cathode so as to minimize heat dissipation problems.
