I think I know the answer to this, but can I substitute a V3207 in IC9 for the stock MN3007?
Also, I couldn't get my hands on a LM7815 so I picked up a LM317 from Small Bear. It's a TO-220. I'm hoping it will suffice as the power regulator.
As far as the IC goes, no you can not... This project is strictly MN3007 only :( The power requierments of the two IC's are different, check the Porkbarrel and Currentlover docs for more info. I'm not sure about the LM317, you should compare the datasheets for a definitive answer

the v3207 is based on the mn3207, which runs on a lower voltage (collosalus pumps 15V into it), and has a different pinout for the power pins anyway.
You could use the 3207 if you're willing to make a little perf/vero daughterboard and leave out the charge pump (no need for a regulator then either).
Isn't the LM317 a variable regulator? That needs to be set with resistors I think although i'm not sure.
You can't find a 7815 or 78L15? They're pretty common (woulda thought smallbear had them)... a 7812 would suffice as well at the cost of a small amount of headroom.
Thanks guys. Small Bear sells the 78L15, so I'll order one at the same time as the 3007 ($10.95! grrr!)
I've got a Lowrider build to tide me over.
Don't know where you are located, and if you need more stuff, but the MN3007 is cheaper at Banzai, on today's dollar-to-euro rate. If you order some more stuff (they have some really nice LED bezels, knobs, IC's, +9V jacks) from them, then it might be worth the extra shipping.... Can't beat Smallbear for Alpha pots though!

Thanks. I'm in Canada. I really wanted to be put on order in at Mammoth today -- they've got a great Black Friday sale on -- but no 3007s.
If you're in Canada, it's actually cheaper to order everything from Banzai. Shipping will be 9 Euro (up to a pound, and that's a lot of parts), and they ship post not courier, so you won't get dinged with brokerage charges.
seems expensive for the 3007.
I can get these for about £3 inc the clock driver 3101.
