SOLVED GCI N.E.W. Apostle rotary caps.

[comradehoser]

Has anyone who has built this managed to make the cap rotary switch do anything? I put in a 100nf for the 68nf and it is still spectacularly inert. I'm really struggling to hear any difference at all. Maybe a 1uf? Put a resistor in there somewhere?

I find this part unclear : "I can't remember why I decided to wire in parallel, but I'm not the only one and I seem to recall it was a designer directive. So, a) if you did, b) is there a reason you all decided to depart from the amp schematics to go with parallel in the pedal?"

Having C7 in parallel is just GCI circuit's layout, that's probably why you "decided" to have it in parallel in the first place ?
What's your point a) exactly ? Can you rephrase it, please ?

I was talking about the FAC rotary itself, not C7, if that's what you're saying.

I first wired the rotary caps in parallel, like in braindrain's posted image up there^. I did it a long time ago, and don't remember why, but it must have been specified by GCI or someone in the build forum since it seems like everybody has done it that way. And C7 is parallel, so maybe it stands to reason that the caps following were also intended to be parallel.

It's an information gap, there's no guidance in the build docs.

What I was saying to you is that if you wired the FAC itself in series and left C7 wired parallel, it could explain why you were getting funky results on the switch. When I did that, it resulted in the voltage drop at Q2 and very pronounced gating when selecting the last FAC position in right-switch mode.

I'm also curious to know if it was a mistake, or a modification to the original schematics with some real purpose.
