Missing Build Docs / Schematics

[szukalski]

Robert, any word on the Argentum 1212 doc? (beyond the BOM, which is here: https://forum.pedalpcb.com/threads/argentum-1212.13976/) I just ordered my PCB. Thanks!

There’s nothing special there, and you bias the J201s to 9v. Anything you’re looking for in particular?

Got a schematic for the Pendulum?

The build docs for the Insurgent Octave Fuzz would be much appreciated!

 

[GratefulEight]

Waiting on the build documentation for the Tellarium Drive. Any updates on when that will drop??

I did the trace on it and have built a fully working one; what info are you needing?

Since we're not trying to revolutionize the layout of pedalboards I've corrected the labels in the drill template. Thanks for pointing that out. :ROFLMAO: Antithesis build doc is up now. sooo excited for the antithesis. i'm not super up on boutique-y pedals so it took me a second but...

Any info about the flock schematic and all the Victory style preamps?

 

[Bricksnbeatles]

Got a schematic for the XS Drive?

The Argentum is running at 18v so bias will be at 9v.

I finished mine yesterday, sounds as e expected. Lovely little pedal, really enjoy it.

I ordered a couple of these boards, but I haven't received them yet. I found the BOM online, but how do I know what components go where? Is the board labeled?

Yes

 

[mralanmorgan]

Yes

Thank you. This is my first build without documentation, I really appreciate it.

Absolutely. The PPCB boards are all like that. You can find another board with the same pot layout for a drill guide. Robert uses a basic template layout for his boards. Makes things easier to build.

This will be my first time trying to do my own layout on in a larger than called for enclosure as my friend wants something bigger. I'm very excited about this!

Is this biased through the trimpots and how do I know when it is biased at 9v?

Measure the DC voltage on the drain of each JFET while adjusting it's corresponding trimpot.

You can use either the through-hole or SMD pad as a test point (whichever is more convenient), regardless of which type transistor you have installed.

Many thanks, once again. I apologize for all the questions and I think that should be the last of them.

Do you mean the Tellurian? I built mine off the board values, it's pretty straightforward and low parts count. Awesome sounding low-medium gain drive.

Is this circuit sensitive to JFET specs? I usually socket SMD JFETs on an adapter PCB, but I'm tempted to just solder them directly if it's not picky.

I've tested & used a bunch of this SMD J201 batch, so I'm not worried about them being super out-of-specs or fakes.

I didn’t find any issues, it’s not a massive gain monster and biased easily.

How about the 680p...can I use mlcc or do I need a box film cap?

I don't think it matters too much, I need to crack mine open to check what I used. I didn't care too much at the time.
