The Kenrad 6A8 is a multi-electrode Vacuum tube of the metal
type designed to perform simultaniously the functions of
a mixer (first detector) tube and of an oscillator tube
in superheterodyne circuits. Through the use of this
type, the independent control of each function is made
possible within a single tube.
The base pins of the 6A8 fit the standard octal socket,
which may be installed to hold the tube in any position.
The heater of the 6A8 is designed to operate on either
DC or AC. For operation on AC with a transformer, the
winding which supplies the heater circuit should operate
the heater at its recommended value for full load
operating conditions at average line voltage. For service
in automobile receivers, the heater terminals of the 6A8
should be connected directly across a 6 Volt battery.
