833A
833A has no equivalent designation confirmed by the archive.
Construction
The 833A is a power triode.
Ratings
The datasheet specifies a maximum DC plate voltage of 2700 volts, or 3000 volts under some operating conditions. The maximum DC grid voltage is 450 volts, and the maximum DC plate current is 500 mA. Maximum plate input is 1800 watts, with a maximum plate dissipation of 400 watts.
Applications
Typical operation is given for forced-air cooling at a DC plate voltage of 3300 volts and a DC grid voltage of -155 volts. For natural cooling, typical operation is given at a plate input of 1250 or 1500 watts, with plate dissipation of 300 or 350 watts.
