Is it OK to run just one ZAPpulse module off of the predator PSU?

I purchased an additional 500VA 40+40 toroidal in order to parallel the two, but now I think going dual mono would be better.

I just got a quote from Henrik at LCAudio for 2 Predator PSU's with 80V caps. The quote for 2 PSU's is US$189. Assuming there's no volume discount here, that means US$94.50 per PSU. Can someone who has ordered this PSU tell me a bit more about what is included? Is it just the PCB, caps, connectors and diodes? I'm assuming it doesn't include a toroid, does it? That seems pretty expensive.

I ordered the soft start circuit from LCAudio, but haven't received it yet. It's not immediately apparent to me from the information available on the website how to connect the soft start circuit. Does the Predator power supply PCB have connectors for powering the soft start PCB? How difficult would it be to use the lcaudio soft start circuit without the Predator power supply?


I have ordered that PSU the transformer i had to buy somwere else (cheaper) i use a 2*50V 1000VA and it works fine.Maybe it had been cheaper to build my own PSU but this one saved me a lot of time and it also comes with warranty if anything should fail.
