I had polystyrene in there at first and now have silver mica. I don't notice any difference either way.

You seem to be using multilayer ceramics for the 100nF caps in the audio path though? That might be a bad choice.

Thank you so much (don't know why but I've felt like I have to post that picture Wink )
That's a real big error ; I took them (C7 C9 C11) for decoupling caps (as C1 & C2)...

I built two but in the end I think I'll just keep one.
So I'm selling one built and tested board for what I paid (which was about 40 euros).
EU preferred (IBAN/BIC and no difficulties with customs)

PM me if interested

all PS3100 PCBs are gone now - shipped 99! hope to see some pictures of the modules you built.

thank you all for the support and suggestions.

BTW what about the 12V? experiences?

If anybody bought more than they ended up using, I am definitely interested in purchasing one.

P.S. Hi, I'm new.

Fonik,

If you were to make another run I would also be interested.

i sold 99 PCBs and have had only little interest since then. the market is saturated, i guess.

I've test few days ago my first pcb and it's smashing

In order to put on panel separate outputs (dry and wet, mostly dry...), I add in parallel 47k to the R10K in the feedback loop, leading to 8k2
Even with this, peak-to-peak can reach up to 14 volts...

for sure filtered signal can be lowered by mix pot with no hurt.

or maybe "custumising PS3000" should be another topic ?

Does anyone have an MOTM style FPE panel made for the PS3100? If not I guess will have design my own.

thanks
pete

Yes, I guess you'd better design your own !

In order to tweak the "bandwidth" of each filter, there's two caps, I wonder if the 100pF is involved (i bet on 1nF) or it's the difference (ratio ?) between the two values...
Is that stupid ?

don't know why but, a couple of switch is maybe missing on my own design Laughing

Nice panel, its huge! but i'm building a single module. Actually i'm building two PS3100's. One for my modular and one for my friend who plays guitar. Is there anything special that needs to be tweaked to make this module ready for guitar inputs?

Dang, how did I manage to miss this!

I'd be interested in one of these also, should they ever become available again. . . .

Finished my panel. And yes, I did incorporate the LFO and LEDs in the end. I do need to get some low current LEDs though, as these are bog standard 20mA ones, which are a bit too much on a 200mA CGS66.

Well, a single module looks a lot better than a whole range of them. I cut the panels by hand, so when you combine a number of them, it starts looking messy...

Yes, please....leave messiness up to us experts in that field. Very Happy

Very nice looking, indeed!

Cheers,

Yes this looks very nice and nobody really cares for the slight misalignment of the modules. Furthermore, you have set an aesthetic of your own. Now you'll have followers...

Actually if your cabinet was white noone would really notice unless they really got up close to it. I say it looks fine and should be nothing to be ashamed of. Looks better than some others I've seen!

Without reading the entire 8 pages, is there a schematic including the LFO section so I may be able to build my own pcb?

By the way, Fonik, in your wiring diagram you end up connecting the last CV into the switch on the audio in jack. Is that on purpose?
