That’s why it’s good to stay with “branded” wall warts, they’re actually made for musical applications? Those “general purpose” wall warts aren’t known to have high/low frequency noise filters.
Thanks BrianQ. That's pretty much what I had theorized, but I really don't want to let the magic smoke out, so, I tend to ask obvious questions. I found a long time ago, with me anyway, that being presumptuous in anything can be costly. (grinning)
Wall warts for stompboxes/mini amps are between 200ma-500ma. Why, because 9V batteries are around the same specs? Look for Roland,Boss, DOD,Danelectro,Dunlop 9v power adapters, there’s a lot of info about them out there. those I mentioned above have been workhorses of the industry for decades? Look at sweetwater or musicians friend
I'll add that those cheap brand walwarts can add a lot of noise and sometimes oscillation sounds to your amp or pedal. So sometimes that old saying that you get what you pay for can be very true. I guess those cheaper brands are skipping the filters that keep those issues at bay. So be careful when shopping for those walwarts.
Sounds great to me. I spent three hours yesterday alone trying to figure out how many milliamps a LM386 wall wart should provide. I would appreciate it greatly!
Ray you might want to try a kit first, seeing it in person helps a lot. While not a Ruby or any other name, these work ok and having a marked board makes it a lot easier. Just a couple bucks on eBay, I have seen them other places too. I switched the headphone jack to a instrument jack. Also I have another one that I want to swap some components to be closer to the guitar amps, hopefully get to it someday.
It might be easier to buy and put together for a beginner, but they aren't a Ruby Amp. It's not just a difference of name, it's a difference of components, component values and schematic/layout. Those shown only have a volume pot instead of a Volume and gain pot like the Ruby has. They will not sound the same.
I think the layouts that BrianQ has provided are simple enough for most people to follow and the exact parts are easy to find at several websites for little enough money.

Thank you Paul, BrianQ. Looks like I'll be checking the music shops online and off.

Another update I’ll do down the line is, adding “External power” to it?

Thank you, thank you gentlemen! This is getting very exciting for me. Kinda like when I started building CBGs. Things are really beginning to "click".
Thank each and every one of you!
