I've spent the last 2 hours surfing for this with no luck. There's a photo at http://www.wah-wah.co.uk/ but no instructions (probably because he sells them!!!
I'm pretty much a newbie, so I thank you in advance for any help you can send my way.
What is the question? So you want a design for a filtered power supply? Or what?
Pretty much. I heard from Stuart about the basic idea, but I was hoping to find a schematic showing exactly what to do to install a DC input on a vox.
Taking a cue from Jack at AMZ, I'd consider a small choke as a power filter. The radio shack one, is too big, I'm planning on trying to locate a smaller one for some bench testing.
But really the best bet is to use a good regulated ps and you shouldn't have any problems and not need any filtering.
Of course if you us a 9v battery, you won't have any problems either.
