Hello David, to answer your comments.

It is never intended that the regulator be used with a battery, for battery use the regulator is omitted and D101 replaced with a link.

The regulator option was added for those (like myself) who want to use an external (mains) power supply.
Initially the regulator was just the 78L09 but in response to a request from BikerHiFiNut (Andy) (see post 108) I made the regulator pad dual purpose to take either a 78L09 OR an LM317 (with the addition of R101 & R102).

I wanted to make the power options as flexible as possible.

Regards
Peter
