I think so, as long as phase inversion (or lack thereof) is not a problem

I recall a discussion a while back in which it was concluded that the CD4050 won't work as an audio amplifier Edit: found it https://forum.pedalpcb.com/threads/expectation-high-low%E2%80%A6.8302/post-75088

Beautiful work! That box is amazing!! Is it 125B sized?

I'll try to record some today at band practice

A single sided layout for what is supposed to be a Lizzard Queen clone with an added an smd path for a millenium bypass

Great job, Guilherme! Looks amazing!

I'm more interested in the envelope detector part of the circuit, actually. I'm trying a discrete jfet approach for the gain stage. Let's see how it works out

Just did what you said and it passes the test, thanks a lot!! I'll finish laying it on the breadboard and listen to how it sounds

@Chuck D. Bones, I've started breadboarding something similar to this one and I plan to use some NSL-32 I've got. Since I'm changing the photocell/led pair, I'm expecting that I might have to change some caps and resistors to make it work. Is C10 in the store schematic the main suspect?

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.
