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.

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

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

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”...

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...

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. :)

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...

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...

That purple is very nice. Is it the LMS powder drop?

Get turbo weird https://aionfx.com/project/xenotron-modulation-machine/ Trem + Flanger + Effects loop = what's not to love? https://www.pedalpcb.com/product/leprechaun/ because 🤷‍♂️ (Speaking of, I need to get mine boxed up)

Cool. I went ground pour on the bottom side trying to keep the big VDC on the top. No way I wanted to pour copper with those big traces. And you’re right, there are some big voltages there on the blue (bottom side). I’ll look at that - don’t know what I was thinking. The 1/16 (whatever that...

Good evening - I like making perfboard layout of preamps, but I'm kind of nervous of the longevity of some of them (one is working, but the ground and +250VDC are literally millimeters apart!) . So, I've taken a shot at putting together a 125B sized (but no tubes!) layout for 2 tubes plus a...

OOOOH YEAH! It’s always the silliest little thing. may the tweed happiness be with you.

Honest question: am I seeing things, or is there no wire connected to the IN of the relay board? I can’t tell and maybe the coffee hasn’t kicked in. Maybe that’s it?
