Thanks! In an earlier post in this thread, I attached a JPG of the front panel design. You can use it as a template for your own front panel. There are also plenty of great examples of hardware and software front panels available online in the Google picture search that can work well.

I recommend getting the 180-day trial of Affinity Designer to create a design that suits your needs. The design I’m using is a copy of the original and not my own, so I can’t share it. Additionally, there are some slight changes—particularly in the gain amount per band—that might not work for everyone.

Since the Sontec layout is quite repetitive, designing it yourself isn’t too time-consuming, and it’s a valuable part of the build process.

This story continues 2.5 years later.

I think in March 2022, so not much after my last post here, an original Sontec 432 showed up on Ebay in Germany and it was a colleague selling it. So I bough a train ticket to the south of Germany and picked up the unit.

My plans to clone a Sontec were obsolete.

Some weeks later another colleague called me if I could help him with information to build his very own clone. I provided him with photos and measurements. Much later it turned out he did some basic research for a clone that in near future would be sold by a well known company. Anyways, a pair of his prototype PCBs made their way to me. And meanwhile I found time to make a front panel and order parts.

I will put 6 of Pier Paolos 992 DOAs on each board. Front panel will be purple. I am kinda tired making black front panels. In the meantime the original unit became a crucial tool to craft the sound I always wanted. I am really curious to see if I can substitute the original Sontec and sell it.

I will start to build all the switches first. I think about finishing the unit within the next year. Since I became dad and studio owner time is very very short.

Is this front-panel image a -- 19" rack-panel -- panel? Is it 4U high? 5U high? And, can you provide a dimension between a couple of the front-panel holes to use as a "scaling reference"? What is the dimension of the switch holes? I greatly appreciate it very much!!!

[Falk]

Sure,

front panel is 4U - like the original. X spacing between the holes is 54.5mm Y spacing is 60.75mm

The dimensions for the holes depends on the parts used and can be found in any product data sheet.

Today I built DOAs from @ppa to be used in the signal and filter path. I also finished the signal boards. Still missing the PSU board which comes from @[silent:arts] Not sure if I ll find time to assemble the unit this year. Good things take time.

Best!
