Here's a list compiled from the photos section of parts for the auto-
switching unit. These parts will need to be picked from stock such
as Radio Shack, etc. If you call your supplier they will need to
look up the parts from their own catalogues to find part numbers. It
is not practical to get the part numbers from various suppliers for
these things. Only a couple of people a year will ever bother to
build one. The godzilla device was designed to allow people to
proceed without all this work.
