Nice one! Missed this post originally. Great layout, is this available somewhere?

The pot shaft is 6.35mm but there is a bit covering the shaft as well. Check the data sheet from the manufacturer. 7mm is pretty tight and doesn't give much leeway for wayward drilling.

You can find a couple of DipTrace templates in the link: https://github.com/szukalski/sheepylove-diptrace/tree/main/faceplates tldr; 7mm for pots, 6.4mm for toggle switches. They come pre-drilled. The only challenge you'll have for an amp chassis is the max size, 670x600mm at JLCPCB. Hate to...

They don't sound the same, some are noisy as fudge. I don't know if there is a source which screens them for noise levels. SMD tend to be much better in uniform quality.

@pingpongcomputer your audio path should be as short as practically possible and avoid crossing over itself where you can. Your input and output traces overlap each other, albeit on different layers. This could bring oscillation, especially in higher gain applications.

As a coincidence, AliExpress had 10x 1590lb for €26. Sends like the universe is sending a message.

2SK30A-GR Is what I used in SMD.

They have an Audio Engineering Discord if you ever want to chat with him. Boots Boost is possibly my fav boost. Just clean and quiet. No colouring or preservatives added.

Put it on the Wishlist..

Yeah, this always gives me caution. Normal practice. Sometimes it works, but most of the time not. I’ve never had an issue with the end product though.

Just because some watery tart lobs an IC at you....

These look great!

Hopefully they had a chat with Dave before-hand as a courtesy. Would hate to see this place getting less stuff shared because of it.

Sharing a play piece I made over the last few months and just boxed up. Pedal building (and playing in general) is way down right now due to other priorities, but I have been able to scrape this one together. I love Chuck's GeFet Boost (the Texel is my boost of choice), so I took the design and...

Thanks for catching that! I have had a few things from GPCB and they have all been great!

To add my 2c, I have had good success "flipping" circuits for negative ground. Basically, anything with a polarity needs to be reversed. Generally, the circuits you do this on are not extremely complicated. Charge pumps are great, but..

This was a nice one to verify. I didn’t plan on boxing it, so I soldered the 3PDTs with right angle connectors (for build speed). Needless to say, I regret that and will have some desoldering to do when I’m back from holiday!

The font in the SL library is Milk Run, if you don’t have it installed then that’s the outcome.

I'm not an electrical engineer (EE), but the guidance I found was to keep power separate from audio, especially where charge pumps are involved. Similar with signal generation (ie. LFO). How relevant it is, well that's a different story.

I must admit, the eyes look pretty good. I'm not usually a fan, but you've got a great implementation here!
