Grid cut-off voltage (see note 12) . . . —190 V 1. Each tube is marked with the recommended values of heater voltage, cathode voltage, peak grid pulse voltage and RF drive power. 2. The heater voltage may be DC or AC up to 25 kHz, square or sine wave. It must be stabilised to the marked value + 2%, unless a frequency above 60 Hz is used, in which case the heater power must be maintained at the value given by the voltage and current shown on the test sheet. Stabilisation to +5% for short periods (up to 30 minutes) will not affect tube life significantly. If a DC heater supply...
