LED Orientation for Boneyard

[dfine22]

I want to get the orientation of the LED's on the boneyard correct and I forget. Square pad (+)?

[pryde]

Yes. Square = +

Also for reference, look at your electrolytic caps on the pcb. the square pad is labelled with a "+"

Hey i don't want to make a new toppic, so... About same effect Boneyard:
With what voltage running this effect 9V or 18V because the tc1044 is charge pump??

If it's working with 9V, the 18V will not be better for him, because i miss a point and need a little explanation, sorry

[stecykmi]

the TC1044 is used to generate a -9V supply. It doesn't generate a +18V supply.

[armkon]

but same preamp power up with 15 -15 or 18 -18 will sound better? i have heard opinion that 9V version got less mids and play differen then even 12V version

If you go for +/- 15V, I suspect your components will need to be rated at least 35V, since there will be a 30V difference. I could be talking out my ass.
