I'm building the Madbean Gravity Wave from the vero layout here - http://tagboardeffects.blogspot.co.uk/2016/02/madbean-gravity-wave-earthquaker.html. I notice that this layout specifies a 7805 for the voltage regulator. Yet Madbean's schematic has a 78L05. I can't tell whether it actually needs a full 1w 7805 or whether the 100mA 78L05 is sufficient. If a 78L05 is OK, then I'm wondering why they put a 7805 on that vero layout.
Its just running the PT2399, the little L05 will work fine.
(for reference the 2399 sucks 15-30mA on average, and has an absolute max rating of 100mA)

Thanks for that. 8)
Wonder why they specified "7805", maybe a typo. Anyway, I'm glad I don't have to use the big guy.
Maybe they assume we know as much as they do. I don't. I-))
