I have three 330VA 25-0-25 transformers that I've been using with some old LM3875 amps used for multi-way active experimentation.
I see these transformers would work well with the P3A. Any other designs to consider that would be a step up from the GC?

The plan seems just fine and 350VA transformers will make quite stiff power supplies - more than enough current there for a P3A. For a another decent Hifi amplifier that can drive 4 ohm loads a bit harder and use the available power, consider APEXAUDIO's (Mile Slavkovic) AX6. Its a good sounding amp and you can search the long thread here or there's also a short and shaky video for a quick view of one PCB design featuring TO3 transistors but there are other versions discussed in the thread too: APEX AX6 diy amplifier - YouTube. As far as being a step up though, a gainclone is hard to beat on paper but of course, sound quality is another matter.
