Yes – You can supply PA1CC +/-25-65V (recommended +/-50V) and PA3CC +/-30-90V (recommended +/-65V) – so yes they can be supplied from the same PSU. We do the same on Coolback II 600 at +/-63V rails – PA1CC takes care of the tweeter and therefore has a lighter load (assuming normal dome tweeter and minimum recommended load 4Ω). Theoretically PA1CC and PA3CC will give the same power at the same voltage, but due to thermal and current limitations this doesn’t apply.
