Would hearing aid subminiature direct heated electron tubes make nice Pleiades V6 mic booster amps?

At your risk. Always use a fuse in series with a battery, batteries for safety.





The Pleiades V6 schematic could be modified.


In case space potemtial grid operation is needed then the grid could be left floating and a different higher voltage battery used for the anode.


Attention to any voltage it can be dangerous.
