Hi Steffan / twotower61

Changing the frequency is adjustable within practical limits by altering either
the cap or the
resistor in the CR circuit which give you the "long" time period to changeover.
In diagram
here it is 0.1uF and 2.4 Meg Ohm connected to pin 2 of op amp U1B.

Yes you will need three terminals on the socket ; one terminal (Normally Closed)
to be
switched Open when inserting the plug.

Thanks for the site for voltage increaser. will look at it later. But ... Bob
Beck stopped using
the higher voltage. he changed from 4x9 to 3x9 batts and settled for that. there
is probably a
good reason for that. think skin burns :-).

OK, Tony
