That’s true (forgot to consider that). I was thinking amps that are similar to where Marshall puts their EQ - Hiwatt, etc. It’s more of an exercise in thinking and experimenting. Probably head in the clouds thinking, but makes the two interconnected hamster cages operating in opposite directions...

So, this got me thinking if this overall topology can be tuned to other amps. I will need to grab a breadboard and some frequency sims.

Maybe check c4? It might have overheated something or you bumped a lead and it broke? Not likely, but another place to look. It might not hurt to reflow the connections after Q3 up to the drive pot. One side of the c4 solder joint looks a bit skimpy on the solder

Om Nom is such a fun character in that silly game.

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.

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...

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.

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.

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’?

It’ll be just fine.

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.

I was thinking deuterium as a pedal name.

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:

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...

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...
