SOLVED Parentheses mini Germanium diodes question

[gian]

Hello everyone!

I tried to find the answer to this specific question on the forum, but could not find it.

I have bought a parentheses mini PCB, and I am trying to understand the orientation of the germanium diodes.

• The schematics of the parentheses mini PCB (https://docs.pedalpcb.com/project/ParenthesesMini.pdf) shows that the anodes of the two diodes (D2 and D3) should be connected,
• while the schematics of the parentheses PCB (https://docs.pedalpcb.com/project/Parentheses.pdf) shows that the cathodes of the two diodes (D1 and D2) should be connected.

Checking continuity on my PCB shows that the two cathodes pads (striped end on the PCB) are connected.

Which one should I follow? I guess I should just follow the symbols on the PCB, but I'm wondering why the schematics of the parentheses mini PCB says otherwise.

I am a bit new to this, I'm probably missing something. The fact that the striped ends of my GE diodes correspond to the anodes is also not helping

Thanks for any answer

Here is a picture of my PCB:

I have just noticed that the stripes are reversed compared to those of the reference image in the documentation, so I'm not sure if the stripes of the GE diodes on my PCB indicate the anode or cathode.

Just to clarify: the pedal is working fine, I just want to make sure I get the orientation of these diodes right.

Better if the cathodes are connected. Ge diodes are usually leaky enough for the circuit to work if the GE diodes are installed backwards, but it is not recommended. EQD screwed up when they installed the Ge diodes backwards in some versions of the Life pedal and that error propagated to some of the clone boards.

Thanks a lot!

The diodes on the Parentheses Mini have been corrected as well, the documentation just hasn't been updated to indicate that.

You have the most recent revision of the PCB, install them according to the silkscreen.
