Have to take ESR in elcaps into account as well as derating of mlccs, if you're getting real technical.. What does this mean and how do you go about it?

Nice catch. Didn't even occur to me. Fixed that one. thank you

Yup the design with that decade ladder was for ultra-sensitive digital hardware that went in an airplane, so it was running off 28V aircraft power which can be a bit unpredictable for noise. In a pedal power supply it would be absolute overkill and you likely wouldn't hear much of a difference...

I would strongly recommend (and I'm a little surprised the AI tool didn't mention it) that you add small-ish (100nF) decoupling capacitors in parallel with your 10uF caps on the inputs to each of your supplies. It's one of those "engineering best practice" things we do to further filter...

Here is an updated layout. I feel is better but probably doesn't address every issue. I shortened the layout to make it easier moving and adding stuff.

It's these. https://cdn.semikey.com/upload/pdfs/18/65/18659b153debe925a36f01a330e6da15.pdf second page. I hope they'll work. and now having fully read the datasheet I see that the filtering caps are of the wrong value. I stupidly assumed SAI would know all about what I was after once I...

Hey thank you forum people. Originally (2 weeks ago) I did get B1209-2W. When I went back to (S) AI it then tells me about the regulated version of the same module. This is the first time having ever talked to an AI. I kept up loading my layout and even though I thought I had clearly laid...

Hoping some one with more experience , expertise , and knowledge will take a look at my layout. See if anyone can spot anything wrong or something needs added or removed. Or even general criticism. I'm thinking its good to go and have been refining the layout for a week or 2 and feel pretty...

Echoing all the above. What an absolutely brutal sounding pedal

This is some sad news to hear I was gung ho from the vids to have one. Maybe my build IS what it's supposed to sound like. The vids do get crunchy mine not so much. Well there are plenty of other to build so I'll put this one away Any suggestions ? I'm always up for high gain crunch pedals and...

So glad some fellow builders chimed in. When I uploaded the layout I only had one thing on my mind, does the layout work. Wasn't thinking about the fact I didn't finish color coding traces and pot layouts. To be honest although its more work I don't mind wiring in the pots. and though it shows a...

3rd time on my first layout but ... this one when signal tracing was able to get signal on the output but when I plug my guitar in I get nothing. I use a tone generator off my computer out my headphones jack to the pedal under test. My pedal test rig has a built in audio probe that I use...

Since I suck at reading schematics I figured It'd help my understanding by doing my own layouts. This is my first one and I used DIYLC for the layout. I did the Horton Thexdrive a.k.a. Nutdriver O.D. using the schematic from the build doc. Came out bigger than I'd like but I just want to...

Wiring would the next likely suspect I assume. All values check out. Maybe the other IC is bad? It’s a small circuit so not a whole lot to go wrong. Maybe the layout is not good I did move a couple of things around. I’d love to get this working it’s a great sounding circuit. Hint Hint Mr...

Ahhhh thank you . We’ll take a compliment anyway we can.

I'll get some up as soon as I can . I mean my friend will get some up hopefully tonight. Thank you

i have not tried a buffer yet since I 'm using my test box to try the board out. I don't believe turning the guitar down stopped the squeal but I'll have to double check that. Does that happen to signify something in particular?

So you got this freind who put a Lo Baller together and barely had any effect , upon examination it was found a mylar cap was used in place of a tantalum same value wrong type That would be c3 470nf . Would this be the reason why there is no effect? Can an electrolytic be used in place of a...

Yes twisting turning and moving the wires changed nothing except minor pitch changes in the squeal And with the audio probe I am to probe until i come across a point where it's squealing then try to figure out what component and why? Basically how one would probe for anything else on a non...

Excellent thank you edit : wanted to come back and say i had a couple of tc1044scpa the one I had in the socket was a 1044cpaz. Swapping the cpaz for scpa definitely helped (quite a bit) but didn't eliminate the squeal 100% maybe reduced it by 50 %. Maybe I gotta try several different ones...
