    What's up with Deadend FX? "Temporarily closed until further notice"

    I jumped to the Facey-books and it sounds like they're out for surgery for a couple months. I just needed to know where to find the build docs in case I want to tweak my Purple Playtpus build to bypass the octave setting (because it still kind of bleeds over) so it's just regular LLama.

    Alternative for 2n4062?

    Also, if you wanted, you could flip the polarity of the electrolytics to ground (negative ground instead of positive ground), but you'd have to find an NPN germanium (robert has some good Russian ones that are about 100hfe). Then you could used 2n3904 or some fun old stock NPN silicons (like...

    Alternative for 2n4062?

    Looks like the 2N4062 is a lower gain PNP silicon. So maybe a modern 2n3906 will work. That should get you pointed down the right path.

    This Week on the Breadboard: Shallow Water

    When I get time (unless someone gets to it), I’ll try my hand at a board. I’m not great, but I’ll give it a shot.

    Could We Do This?

    So, they basically had a cathode-biased 6L6 twin? (Well, the fixed bias is still there). No wonder it felt different. Aleph’s “slap a JFet/Mosfet” would be doable. Maybe branching off of ROG’s Thunderbird but adjust the “output” to be more ‘squishy’?

    El Sol - subbing caps?

    It’ll be just fine.

    Stuff you wanted to know but were afraid to ask

    I found it! It’s a place to put a jumper wire if you use a LTC1144 (or whatever charge pump ends in 1144). You find it by where the charge pump is in the schematic with a note.

    This Week on the Breadboard: Shallow Water

    I was thinking deuterium as a pedal name.

    This Week on the Breadboard: Shallow Water

    This is great. Do I have a Shallow Water? No. Do I need to build Chuck’s Heavy Water? Nope. Will I probably put it on the pile of things to build? Likely:

    💖 Stay Alive ✨ Top Five of '25 💖

    So far this year (because I have about 3-5 that I might be able to finish before the end of the year), but in no particular order 1. Deeptronics Freeze module pedal 2. Nobels ODR-C 3. Fuzz Aldrin (but still testing a few transistors) ** ** this ranking is under review (I was checking voltages...

    What's your nemesis circuit?

    sitting on the sidelines of my workspace is the lectricFX flanger. But I need to get other things finished before I try again with that.

    What kind of pot is this?

    Looks like a reverse audio taper 1M. Better send it to me for disposal. :)

    Sparkly tone machines: Paragon, Closed Circuit Booster Limiter and 401K Compressor

    I award you 3/3 glitters. Curiosity - are you painting these enclosures glittery or do you have a glitter supplier?

    Tube Preamp PCB (draft)

    I did try the tube connections on the edge of the board, but it got kind of clunky. I like the idea of of the grid resistors off board, especially since it will just be for myself. And the parallel trace in that D3/R19 was a “I know it’s parallel but I can’t make the layout any prettier”...

    Tube Preamp PCB (draft)

    As my college football team was getting its teeth kicked in, I decided to work on this layout. Here's revision 3. I think, think there's at least 2mm between traces/holes. I used pads for the tone stack (I know, that part isn't pretty). I also moved the 275v to the top area of the board (with...

    Tube Preamp PCB (draft)

    Self reply. Man, I always screw up where ground loops would/would not be. I’ll give it a shot and have you tear it apart. :)

    Tube Preamp PCB (draft)

    I shouldn’t probably post when I’m a bit tired: I forget context. And yes, you’re right: the airwires are Ground connections. 1. I calculated 1.25 somehow, but I’ll probably move it to .75-.85, just to give myself a bit of leeway. 2. Good thoughts on the signal being smaller width. 3. The...

    Tube Preamp PCB (draft)

    So, I gave it another shot, this time in landscape. Little wider and narrower. Guess I went Hiwatt style. :) I did move some of the potentiometers from the bottom up a couple millimeters (my grid is in 1mm squares). Everything should have 1.5-2mm clearance, all HV is on 1.25mm traces, and I...
