Default 5 channels class-T amp Power Supply

Hi,

It's not because my AMP4 is not yet fully functional that I shouldn't continue to think about my future design.

I'm planning to build a 5 channels amp and I selected a 500VA 15V transformer for the power supply and at least 69000uF caps (cumulated).

But since my 80VA 15V power supply already blows the 2A slow blow fuses (on 15V side) at inrush, for the 500VA, I want to add a soft start.

I've found a lot of design, but since I can't make PCB, I'd like to find a kit.

What do you think about this one : http://lcaudio.com/index.php?page=12 ? (go down to "Soft Start Circuit")

Will it fit my needs?

Thank you...

It has functionalities I don't need and it's twice the price... But I'll keep it in mind.
