New Etcher's Paradise Project: Dragonthlayur - the EHX Lizard Queen

[jimilee]

I did use 100nf caps, yes.

nah, I mean, did you use any special flavors of 100nF?

No sir, just whatever Tayda sells.

Got my Dragonthayur board working! Like I said, many mistakes in my design that I'm rectifying, but overall, I love the sound. One weird thing: I've seen other schematics (and the Lizard Queen) call out different component values for the transistors, and particularly Q1: I was getting almost no signal out until I changed Q1 for a Darlington (MPSA13 per Brian's schematic). Started out with a 2n2222, and it reads good before and after, had solid joints too, so no idea what was going on. But it works now!

revised layout (so far) in a 1590B with 19mm Davies knobs and non-sub-miniature SPDT


and with 13mm Davies knobs

new board is still spaghetti and looks awful, so no shots of that yet

1590B will have side jacks. My working model is a 1590N1/125B, so it gets top jacks. That thing, though, is uglier than my board (really bad PLA print AND bondo...yikes)

Nice work on this one, Brian, sounds great and the white LED lends a nice tonal variation. Now to finish up the hand-etch board build.
