neon indicators

[Scott Gravenhorst]

A typical neon lamp, like an NE-2 has a turn-on voltage 
of about 65 volts.  A current limiting resistor is required.  
Although they consume less current than LEDs, they 
require an extra supply voltage and perhaps somewhat expensive
transistors to control them.  This PS voltage would not need 
to be regulated, but it is a rather high voltage, say 90 volts
which presents a hazard that the usual solid state synth
does not normally present.  Getting nailed with 90 volts is
only a little more fun than 120 volts.

LEDs can run from 5, 12, 15 or whatever and can use easy
to find and cheap transistors to drive them.
