Miniature type used
primarily as output
amplifier in automobile
receivers and in ac-
operated receivers.
Requires miniature
7-contact socket. Within
its maximum ratings, the
performance of this
type is equivalent to
that of larger types
6V6 and 6V6GTA.



Heater Voltage (AC/DC) 6.3volts
Heater Current0.45ampere
Heater Warm-up Time (Average)11seconds


Peak Heater-Cathode Voltage
