Ordered ~$60 worth of stuff on Friday, Global Standard Direct. It arrived the week after Tuesday, 11 days later just like you said. I can live with that. Honestly DHL/UPS is... best case... 7 days. As long as it shows up, I can wait an extra 4 days. I've got another order soon that will be...

I asked this over on AllAboutCircuits. Great thread, especially the Cyril Bateman articles. Also the TI article in post #2 is fantastic. https://forum.allaboutcircuits.com/threads/film-capacitors-for-audio-in-smd.208074/

I love these things, made by Daier: Tayda has 6-7 different options (red, blue, green, purple, red/green, blue/red, momentary, etc) for $3.49. Amplified Parts has something similar with a bigger knob for $8.45. I don't like the big knob or the price. Aliexpress has a 10 pack for $45 shipped...

Tayda Yesterday - DHL: Not terrible, but a far cry from what used to be $20-25 to ship a larger order like this.

Cool. Here's the BOM and cost estimate (minus boards). The part costs don't include shipping (mouser, stompboxparts, Tayda, etc), so factor that in. It's not a cheap build. I could sell the 2 PCB's only or do the whole kit (except enclosure at this point). Google Sheets BOM

Ah, I’ve wondered about THD, I’ll look into REW!

I settled on this for the power section. It seems fine. And using the 2W version has plenty of current capacity, I don't think the 3W is even remotely necessary for my application, about 200mA at 9v. Currently mouser has the 2W for $11 and the 3W for $15 (+tariffs), but the 3W is often out of...

A few years ago I bought a good scope for troubleshooting, a Siglent SDS 804X HD, which is a pretty nice beginner scope for $350-450 (2 vs 4 channels). Probably way more features than I'll ever figure out, but I'm learning. One of the reasons I needed a scope, I'm designing an acoustic preamp &...

A recent picture of this project, a Bode plot of the parametric mid. This version of the PCB is a 4-layer I designed in EasyEDA, much improved over previous version. I made mistakes converting the schematic from Eagle to EasyEDA, fixed them. Now re-printing. Should have the final version here...

Well I was wrong, it IS <$60. Allows you to do Global during the "estimate" phase, but when you go to checkout, it's strictly <$60, even says $59.99 or less.

Just put $63 worth in my JLC cart, Global is available for $3.37! So maybe $60 isn’t the limit but I’m sure it’s close to that.

Acoustic Preamp, designed similar to Grace Designs Alix.

Back to this Global Standard Direct Line shipping... what's everyone's experience with it? The standard DHL is actually pretty fast, like 2-3 days from when they ship (I guess that's what it says too!). Does the GSDL really take 8-13?

Whoa, that was it. If I pick standard green and forgo the color upcharge (keeping merchandise under $60), I can checkout for $56.70 total, compared to $140 by picking a $5 color upgrade. Shipping is WAY less. There may be fees on there I don't see yet, but still 1/2 as much as if merchandise is...

Maybe it's the size of the boards I'm making? Mine are 126 x 56mm. No way 10 boards of that + the box is 1.5 kg. idk.

Just checking a JLC price, the Global Standard Direct option doesn't appear to be available... or at least I couldn't find it. Last fall I bought 5 each of 2 different boards, with shipping/fees was about $70. Now, $140.

I struggle with this, seems EXCESSIVE. Sure, open the outer box and let the sit for an hour. Then open the case, let it air out for a few hours before you tune it up. Use common sense, does it feel like it's at room temperature or is it still cold to the touch? YMMV.

@joulupukki got it working! Load your own standby screen image.

Oh wow, didn’t know that. Yeah that would be cool to have that option!

Dang you're right about the Global Standard Direct, that would've saved me $20 (and taken 8-13 business days for shipping instead of 2-4). I've used Oshpark before, but in the case above it's $600+!! PCBWAY.com is another I've read about, not sure but it seemed in a similar price range as JLC.
