The MSK 1933 Series of High Speed, High Voltage Video Amplifiers are designed to drive the grid of today's high performance CRTs. The MSK 1933 has user adjustable contrast and brightness levels and also comes with a blanking function. The MSK 1933 can be directly connected to many video sources including RS170, RS343 and high speed video D/A converters. The MSK 1933 is available in four versions for different applications. The MSK 1933-0 has no internal high voltage resistor or inductor allowing the user to dissipate much of the power externally. The MSK 19332, MSK 1933-4 and the MSK 1933-6 each have an internal resistor-inductor designed for optimum bandwidth. The MSK 1933-6 has slightly lower bandwidth but can be operated from up to -120V. Each version of the MSK 1933 is packaged in an isolated 22 pin insulated ceramic substrate that can be directly connected to a heat sink using standard mounting techniques. The leads are available straight out, bent up or bent down.
