Simple... transformer, bridge rectifier, some capacitance.

I'd say 300VA transformer 30VACx2... and about 10,000uF total capacitance per rail.. i'd go with 2x6800uF per rail personally.

if 40 turns of wire and a few resistors is overkill, I gladly go for it...

Thanks for any help .
Right now I'm building the DoGC MKIII version design by Dr Bora but I read so many positive comments on the Techno amp I want to have one .

Greetings

Try Dr Bora s website, its on his profile page. If you dont come right I suggest you contact a member called victor1986. He has built most of the designs and I believe he actually designs the pcbs for Dr Bora.
