Old API 525 c Pinout Update

After digging on the interwebs for readable pinout mod info on updating an old 525 to the new API format (and coming up empty), I emailed Brad at avensonaudio.com and the service center at API. Both of them came back with this pinout diagram. It currently does not reside anywhere on the internet so I'll post it here for those interested. Thanks Brad, thanks Jordan!
