Re: Any current Serge panel kits available?

WOW ... had not seen that these were (again) available :goo: :goo: a bargain! Elby have a range of panels and a load more coming out in March. Have a proper look or check the threads here. Panels with separate PCBs as per the old days. https://www.elby-designs.com/contents/en-us/d79_Best_of_CGS_-_BO...

Re: Help me identify this serge DSG PCB

Speaking of which does anyone remember "Electronics for Music" it was a web site run by a guy that made PCBs for synth stuff. I bought a bunch of PBCs from them. I think it was run by a guy named Tom Gamble? I think this might win: https://yusynth.net/index_en.php?&arg=4 Yeah, Electronics for Music...

I haven't done the yusynth version, but the CGS version behaves similarly... I think it may be inherent in the design. one of my favorite VCFs.

i use Front Panel Express for my panels. I provide FPD files for all of my modules on my website - you could use those as starting points and edit them for other modules.

first, the cost of official buchla has always been high, and legacy stuff fetched ransom collectors prices… compared to those, the DIY stuff is a bargain. then, there was considerable work to reverse engineer designs from faulty schematics, and updating designs that relied on unobtainium parts. folk...

Big shoutout to Mike Peake for pointing out an error on my Buchla RingMod boards... one of the resistors marked 10r should in fact be 10k. I and others have successfully built these with the marked values, but trimming will be easier with the correction. I've updated the build page with errata and p...

i'm not a euro guy, but i made an exception for Mssr. Mobenthy, and i have a small rack with one of each, but sadly no room for the Grassi. it occurred to me that, if it's closely related to Mr. Grassi paper circuit it might not need a bipolar PS, and might even run on 9v battery power, which turned...
