Yes, I've learned this lesson as of late. I ordered a Kliche Mini Special box with the default PPCB Tayda north-side jack locations and it didn't work. I've started moving the jacks closer to the lid side edge on recent drill templates.

Looks great @Barry! All good with the drill template? Thanks for the tip about the pot taper on the gain.

Hey @MichaelW - yes, tried that and didn't have any luck. I may have a different issue because I found a bad WIMA film 220n cap in that part of the circuit and replaced it, then the signal looked much better, but resulted with the 'unity gain' issue using both 4580s and 4558s (in both IC...

Glad I found this thread! I'm having the same issue with the gain knob not changing the signal (looks like unity gain through the op-amp on o-scope). Changing to 4558 did not help my situation - both sets of op-amps purchased through Mouser. Any other ideas?

Nice work! I got (re)-started with DIY a few years ago by building a dozen Aion kits.

Great build! I'll have to try some of these tube DIY builds soon.

My favorites are the Glory Hole, Pro-10 (blue side), and Aion Cerulean. I sold an older Aion Cerulean kit build which was a dumb decision as the new version removed the JFET output gain stage. I occasionally hear strange headroom issues, ghosting or overtones (undertones?) from the Pauper...

Looks great! This board is on my to-do list for January or February.

Great work! I've been hunting some JST XH cable assemblies like Aion uses in their kits to make the daughter board connection less of a headache. The only ones I can find are 10cm and longer which is more length than required. I wish Aion would sell the 70mm 3pin assemblies as a component item.

Great job! Thanks for the pro-tip about joining the boards first, then soldering both sides for clearance check/test!

I used to use OrCAD to do work related schematics and PCBs in the early 2000's and I attempted Eagle once and stopped within minutes. Not happening for me...

If you can get the calligraphy in a digital format (preferably a vector graphic format like SVG), it makes it easy to work with for Affinity Designer 2 or other programs that can generate the PDF necessary for Tayda. My guess is that an iPad or similar with a drawing device could be a solution...

Thanks for the complements on the graphic. I agree on the great resources here and they helped me a ton! I'm using Affinity Designer 2 and a lot of my graphics are Etsy SVG files or similar ways to get started without much 'designing'. The Aurum posted here was artwork created by my wife who...

3266W will work in the existing footprint as a 12-turn trimmer. I used that for a recent XC Phase build. https://www.bourns.com/data/global/pdfs/3266.pdf

Quick update - this one was built and verified as a fit to the PCB.
