Twin Diode - High-Mu Triode
The 12AV6 / HBC91 Vacuum tube is a miniature type used as
a combined detector, amplifier and
AVC tube in automobile and AC-operated radio receivers.
It requires a miniature 7-contact socket. The 12AV6 may
be substituted directly for the 12AT6 in applications
where the higher amplification of the 6AV6 is advantageous.
