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.

Look at the PSU on this site... nice simple and effective...

Personally i'd say that's overkill... but thats my opinion

Feel free to try it.

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

Hello

Can someone share the PC board layout for the Techno amplifier .
Today I purchased all the components for these amplifier trusting I will find somewhere the layout ..
Now I invested a lot of money to these amp and with out the PC board lay out I'm unable to go further , to build the amp .
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.

Hello

Thanks for the reply , I checked already Dr Bora website and only the schematic available .
I asked Carlos because he just finished his Techno but I only I get from him the green layout with the components .
With that I'm unable to make PC boards .
Yes is a good idea I will contact to Viktor may be He can help me .

Greetings
