Thanks!

Hello, Are all three JFET in the pedal supposed to be biased to 9v? Q2 has 18V going to it, and I can't get it lower than 14V with the trimmer. Thanks!

What is the hFE of your germanium?

Thanks!

Hi, quick question. With this relay system : https://www.pedalpcb.com/product/pcb393/ should my switch be normally closed or normally open? Thanks!

@Robert you know what Pedal PCB should do? Post complete build docs at the same time as the PCB release. I'm done buying PCBs with no parts lists or schematics or drill templates. It's just pathetic at this point. Need some help getting caught up? I'd do it for minimum wage! Seriously.

Thanks! Fixed.

This took a while, so I felt like sharing. https://drill.taydakits.com/box-designs/new?public_key=R0pOa1d4MzQzVUNpY0ZyRnA0bFQ0QT09Cg== P.S.:Has been modded for 2.1mm panel mount non-switching DC jack.

Thank You! Came here today hoping someone had done this. Nice work! 👍

Nope.

Thanks!

Looking forward to making the tone generator. Will require an order of SMD parts. Could we get a list? Also, what is a “milled” enclosure?

Well, I am passing signal through the effect now, but it doesn’t seem quite right. The S/H is really slow even when turned up all the way. LM13700 6 -6.3V 11 +6.65 The op amps are both -6.55 on 4 and +7 on 8. There’s something weird with the voltage coming in I think. As before, supply is...

LM13700 6 -6.32v 9 0v TL072 1 4 0v 8 +7v TL072 4 -3.5v 8 +7v My supply voltage is 9.46v until I connect it. When connected it drops to 7.3v. Is that normal?

Hello, I have been trying to build a Minnow. My first attempt had a few issues, so I started over with a new PCB. One of the issues was that the +8 and -8 were reading +9 and -9. On this new board I decided to start by just populating the power section, and I still have the same problem. What...
