CV271 fluorescent indicator
This indicator measures
48x17mm overall and has a B7G base.
This
is an argon filled fluorescent indicator tube with a willemite coating.
Information on what this
is designed to indicate is needed. However the test data says a
modulated RF voltage of 27V peak value at 45MHz, modulated to 100%
at 50Hz is applied to the anode from a 150 ohm line loosely coupled
to the source of power, and the filament voltage is adjusted until
a glow occurs.
