[sdiy] WTB:SAD512 chips

I believe I read that SAD1024 chips can be used in an ARP Omni 2
chorus board. The particular type of SAD512s used in the Omni 2 have
the same pinout as an SAD1024 with only one of the halves wired up.
Apparently, there were some SAD1024s that were manufactured with flaws
that disabled one of the delay lines. So they wired whichever delay
line was working to one set of pins and called it an SAD512! There are
also different SAD512s that have fewer pins.

Someone correct me if I'm wrong. I remember reading this somewhere,
maybe on this list.

So if you are building an Omni 2 chorus board from scratch, then you
can probably use small-package SAD512s or SAD1024s in place of the
large-package SAD512s and it will still work.

If you are building one from scratch, but are using exactly the same
layout as the original Omni board, then you can use either
large-package SAD512s or SAD1024s.
