Which capacitors on the IIsi see 12v?


Well-known member
I am restoring a couple of IIsi machines. I have gobs of 16v tantalum caps that I'd like to use up, and I have a handful of 24v tantalum caps. To avoid capacitor derating issues, I'd like to use my 24v caps in places where they will see 12v. For caps that only see 5v, I'd like to use my large supply of 16v caps.

Does anyone know which capacitors see 12v on the IIsi? The only cap connected to the 12v rail that I can find is C38. None of the others seem to be directly connected to 12v.
