Default Aikido Headphone Amp

Hi Fellas!

I just ordered the PCB from Mr Broskie's site to get started on this.

One thing I didn't realise after browsing a bit further, is that I will need to make a PSU.


What, after all, is a PSU and how can it be done?

I did some googling and read through his blogs, it appears to power the main part of the amp, but is a really contentious issue amongst all the DIYers out there.

Any hints?

Check out a couple of my posts explaining how to do that.

Poll..anyone interested in an Aikido linestage PCB group buy?

After a while you'll run into this schematic which I've built and it works like a charm.

Maybe you should all implore JB to sell a psu pcb as well.

PS...I'm not selling Aikido boards or psu boards.
If you can see the speaker cone's not hifi.

Hi Tom

Be sure that you understand everything that goes on in that PSU. I do not want to scare you, but it can be lethal!

Please have a thorough view, or better, understandeing, of what is written in this thread!
Safety Practices, General and Ultra-High Voltage

Good luck with the project
