What on earth is that power supply circuit all about? He has two 9
volt batteries, just like me, but instead of using the centre point of
the batteries for ground, he has put in a pair of resistors - which
drain an extra couple of milliamps from the battery. If he had just
used a double pole switch for power, all that silliness would have
been avoided.

Well Don if I was you I'd ask him myself.

I'm not sure I'm *that* bothered. It just seems a little odd to
increase the battery current drain by 50% when you really don't need
to.
