Does anyone have a live link for the LPG fix? The link appears to be inactive now.

VCA mode is very cool anyway!

Cheers!

It should be in the zip file here:

Please let me know if it isn't. I will find another copy and upload it.

I was having the same problem - I've got the Unopole working with these values (it's a Rev1.1 board and I used 4.7nF for C1) - thanks !

Same thing with the FadeX, there is a schematic for the SMT LED Driver, the FadeX portion, and the additional level VCA that was added recently.

The BOMs are arranged in the same way. One BOM per section. So for a Dual VCA you need two sets of parts. Same for the Dual LPG, and so on.

Anyone have copies of these files? I have some old PCB's sitting around and I would like schematics etc.

Do a search for "stroh docs"

It will give you a thread with a zip file of all of these and more.

Hi fellow builders, I'm about to start a dual VCA. For the pots, Lin or Log ?

Can't wait to try the DLPG! Happy holidays!

Edit: The following offer has ended:

Per the holidays, I'd like to offer some of my VTL5C1 stash to Wigglers...I believe there are two per DLPG PCB; I'll send for free, up to four 5C1 to each of the first five who PM me, for people building one or two of these (I'm going to try a Buchla-style 292 panel). I'm setting aside 20 so if some people are only after 2 I'll be able to spread them out to even more folks. Thanks J3RK for the great projects!
Did you end up building some of these behind a 292c panel? If so I would love to see pictures and hear how it turned out. Also it would be interesting to know how it compared to a Buchla 292c.

I ended up not sending 5C1vactrols to everyone I'd promised...my apologies!!!

I built a couple of these boards but they're in a box of backlog, never compared them but do love the Stroh projects!
This is not the place I'd imagined it to be.
