That's it, the zeners are the clipping diodes

Just FYI, Robert has already posted a schematic for the cobbler: https://forum.pedalpcb.com/threads/ppcb-cobbler-victory-copper.15569/post-180926

Realistically, I will probably never build any of this, but I love where this is going

Nice, thanks!

Great, thanks! I'll have something in the breadboard later today. What exactly are you calling a cold bias?

Ressurecting this since my breadboard is empty after a long period, even though my question is not entirely related to OTAs. Is there a discrete approach that could give me a result similar to this 2nd harmonic behavior? I'm guessing it would be a really bare bones OTA of some kind

Just played with it again. RF makes for most of the noise and breathing did not even bother me all that much (now that I know it happens). I'm boxing this one up

I'll see what I'm able to do without destroying the board, might even try a switch or a potentiometer there. And I can live with some breathing, specially if I manage to reduce it a bit

I'm guessing, it's mostly hum and RF, but to be honest, after I heard my bandmate's CS3, I'm not that worried about the noise floor (my ET is probably less noisier even outside the box). I might tinker a bit with the release time (built with the suggested 470k), though, to see if I can tame the...

Just got a couple of those modules to try! I've been looking for a good solution to give me ±15V for a while

Small update: I had originally used 2n3819 fets (selected for vp in the 2V vicinity) and it wasn't compressing as much as I would want, so I've decided to try different fets and rebias. Now with 2sk246 it compresses nicely and the "Limit" pot is useful in the full pot rotation.

I'm pretty certain the album is not my brazilian favorite, but I can see an argument for it being the goat

I still have to figure out how much detail I can manage with this kind of technique, but I like the results. And the process itself is very fun, mixing different inks, carving the linoleum. Feels like the ultimate diy experience :LOL:

Thanks! I'm happy with it! Just wished the labels were a bit more clear. My linoleum has two textures: one side is smoother than the other, and I did the artwork on the rougher one

Enclosure is bought (I lack the tools and the ability :LOL: ), I just did the artwork

Built myself an orange squeezer with a threshold control as implemented in the Orange Smoothie. Nothing much to write about this one, but it does the job and is quite silent for a compressor. Will probably go to the pedalboard. Did some linocut for the artwork, but used the rough side of the...

Nice job!! Have you had any noise issues running the 3 charge pumps from the same power inlet?

That's good to know! I can definitely hear compression (the engineer thumb has more compression available than I find useful, actually), but this behavior was throwing me off. It should get a little better noise wise when I box it up

Hello everyone! I've built an engineers thumb according to ValveWizard's schematic (schematic here) and it compresses as it should. However, depending on the settings (mostly higher ratio and lower threshold combined) I get this weird artifact where it feels like the volume (and the noise) is...

Temol, what kind of input signal are you using for this transient analysis?
