FIELD: electronic devices. SUBSTANCE: in vacuum-degassing mode of operation, collector output operation during emitter heating is estimated by measured values of heat flow from emitter, insulation resistance, short-circuit current, no-load voltage, and estimated temperature of collector. EFFECT: improved accuracy of estimation. 1 dwg, 1 tbl
