[sdiy] +/- 9v synth circuits

[Ryan Guilfoyle]

Thanks for the ideas guys! (spec the part about
headroom) How about this, two 9v's in series per rail
into 7812's,that will give me the headroom for the
regulators even if the bat's go a little flat correct?
The only reason I'm thinking about regs is for tuning
stability. The wasp idea is a good one too, iirc
someone was thinking about cloning one of these with
midi as a commercial project. The main reason for
using batterys is for my commute to school (no outlet
on busses)and the fact that I hate wall warts. I am
shooting to make this thing semi-modular (ala evenfall
minimodular, I have one and it rocks). If the 4 9v's
and regs can do it I may just build up the madmouse
board ive had forever and save myself some dough.
Two more questions, how can I figure the max current 2
9v batts in series can give me, and does anybody know
how much current a madmouse (the non-midi one) draws
per rail?

Once again I'm amazed at the mass of knowledge on this
list.
