摘要：

As result of INR RF system upgrade new vacuum tubes GI-71A and GI-57A were installed in the final and driver stages instead of GI-54A and GI-51A, manufacture of which had been stopped 20 years ago. New tubes are distinguished from former ones and a problem of optimization of the power amplifier mode of operation became the main one. This is connected not only with new type of the vacuum tubes, but also with the necessity of using, as much as possible, the former power amplifier basic hardware. The paper consists of two parts. In the first one a way of the PA vacuum tube load (equivalent resistance) calculation is considered. In the second one the model for determination of vacuum tube mode of operation is presented. By means of the model the vacuum tube specified in parameters, such as plate voltage, grid-cathode automatic bias, anode load etc, allow right now determining output parameters and efficiency of the power amplifier.
