16A8
16A8 is also designated PCL82.
The 16A8 is a miniature duodecar type tube used in television receiver applications, combining a triode and a pentode in one envelope.
Construction
The 16A8 is a duodecar type requiring a 12-contact socket. Its heater is rated at 16.4 volts ac/dc and 0.6 amperes. The tube has an average warm-up time of 11 seconds. The maximum heater-cathode voltage is ±200 volts peak and 100 volts average.
Applications
The triode unit of the 16A8 is used as a vertical oscillator or as an audio-frequency amplifier. The pentode unit is used as a vertical output tube or as an audio output tube. The tube is also used in vertical-deflection-amplifier, vertical oscillator, and sync-clipper applications in color television receivers.
Ratings
In vertical deflection applications, equipment should be designed around a peak cathode current of 200 mA for the triode section. For the pentode section in frame output applications, equipment should be designed around a peak anode current not exceeding 100 mA.
Type 8B8 is identical with the 16A8 except for heater ratings.
