Power Pentode
VT-1988A is the Military designation
for the 6G6G Vacuum tube.
The 6G6G / VT-198A Vacuum tube is a glass octal type used in the
output stage of radio receivers where moderate power
output is required. This type is economical because of
its low plate-power requirements and low heater
current.
This tube requires an octal socket. Except for
interelectrode capacitances and plate resistances of
175K, this type is electrically identical with type 6AK6.
