Twin Diode
The 12AL5 Vacuum Tube is a miniature, high-perveance
type used as a detector in FM and television circuits.
It is especially useful as a ratio detector in
AC-operated FM receivers. Each diode can be used
independantly of the other or combined in parallel or
full-wave arrangement. The resonant frequency of each
unit is approximately 700 MHz. This tube requires a
miniature 7-contact socket and may be mounted in any
position.
