Default Hiraga 30 watt. Advice needed

Hi Folks.
I have just purchased 2 Hiraga 30 watt kits from Jims Audio on ebay,

Hiraga super 30W class A amplifier kit ! | eBay

I also purchased the transistors he sells for these kits, but my question is what power supply etc I need for this.
Reading all the info I can on here and on other websites has left me pretty confused as to the best way to complete this project. Some other builders are using massive caps. Is this the way to go? I need advice on the power pcb. Is there a suitable kit and what transformer would be needed?
Any help would be fantastic.
Thankyou.

The 2SA872 is a 90 V device, 80% of 90 should be good for the power supply.

Thank you, but I'm really looking for a suitable pcb kit for the PS, plus reasoning behind the massive caps some circuits are using, and advice on a transformer to compliment the above.
