Aikido Headphone Amp

lordearl · 14th June 2007, 01:03 PM

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.

HMMM

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?

Cheers,

Tom

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.

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
