Zener for imp v2

[Zerstorte Zelle]

Hi all,

Ordering the parts for the imp v2 and wondering if a different voltage zener could be subbed. small bear looking like only 8.2v and 12v available.

any recommendations?

best,

I'd suggest just using a 9.1v Zener then.

The 12v would be okay, but the max voltage of the ICL7660SCPA is 10v, IIRC. So if you accidentally plugged in 12v to the pedal the charge pump might become damaged. Not necessarily, but it could happen.
