Yes, it's "just a PN junction" - but it may well have different current-voltage behavior compared to your favorite diode. There are several well known stompboxes that use transistors and FETs this way for different sounds. E.g., check out the measured quantities at...

Congrats @Alex Kenivel ! Troubleshooting takes persistence, and you have it! And it also actually helps you more deeply understand the circuit. Keep on building!

I didn't find the post yet, but here's a generic Rosetta stone for Cyrillic

@Robert sells the 1T313A and 1T313V transistors on PedalPCB, so I thought I'd post the datasheet for this series. Here I've posted the Google translation of the original Russian datasheet available at https://alltransistors.com/adv/pdfview.php?doc=gt313a-b-v_1t313a-b-v.pdf&dire=_russia. Of...

Wow, impressive work @leadfoot !!!

Visually, all the part values that I can see look correct (harder to see values on electrolytics). So good job there. My comment would be to use LESS solder. You want enough to connect them, but adding more isn't necessarily better - too much can obscure whether the solder has fully wet the...

I believe the sticky "mystery" coating is a protective layer against corrosion from salty sea air during trans-Pacific container shipping from China. You see an even thicker anti-corrosion coating (made of a different oilier composition) on large machine tools coming to the US from China as...

Sorry, I'm not sure what you're asking... Look at the datasheet for the specific OTA used in this schematic (model # for IC1 is not shown in the snippet you posted above) - but the output is on pin 5.

It's an OTA https://en.wikipedia.org/wiki/Operational_transconductance_amplifier

True, but only at very high frequencies, e.g., well above audio frequencies, more like RF. At audio frequencies, the electromagnetic penetration length is much longer than the thickness of a can. For example, at 60Hz the electromagnetic penetration length for pure copper is roughly of order 1 cm...

@Robert shunted his inductor on the Stock Fuzz - See https://forum.pedalpcb.com/threads/whats-on-the-workbench.4225/post-390501 I bought my inductor from Mouser

@Robert - Any estimate on when the Sea Monk will re-appear? Are you redesigning the PCB? (Thanks in advance)

2 possibilities: OKKO Holy Grit uses BC182B. D.A.M. Meathead uses BC182 for Q2.

In my post above, I just copied what Mouser emailed me this very afternoon.

An IMPORTANT point regarding eliminating whine due to charge pumps: When a charge pump is giving you a whine, make sure that you are using good quality (low ESR) capacitors for the capacitors used by the chip as part of its charge pump charging action. For a TC1044, those caps are typically...

@ac30irons - looks so cool, I already had my enclosure design made as a vinyl UV-printed sticker!

@swelchy - Hats off to you for being a good father!

Note added: sadly there aren't good data sheets on germanium diodes that go down to low voltages and currents, especially in reverse bias. But people here have posted data and also discussed the impacts, especially @Chuck D. Bones
