Hello Ken,

The 6F6 metal tube has the same dimensions as the 12A6.

Converting to 6 V tubes puts a heavier load on the heater wiring and remote
control switch. Not good.

The Australian government had Command receivers' heater circuits rewired for
the Avro Anson aircraft, which is a 12 V machine. And then used DM-53Z 12V
dynamotors.

I know that too, Brian, but the 6F6 is a much taller and fatter tube and
won't fit in the radio 
with the covers on.

In any case, as far as I am concerned, converting the radio to use either 6
V tubes, or to 
change to all parallel filaments are really stupid ideas.
