Functional and affordable

This is a straightforward build that someone with a little experience could easily tackle.

If you use a regular, shrouded 10-pin Eurorack power connector, instead of a right-angle one, the notch faces the faceplate - don't get confused by the silkscreen.

Make sure you can source a legitimate NE5517N or LM13700 before purchasing, as the DIP version is getting harder to find.

Suggested improvements:
- Reduce the panel side of the board about 1mm so the panel rests on the jacks not the board edge.
- Use a larger footprint for the through-holes so it's easier to solder, especially on pads to ground, as it's hard to keep the iron tip off the ground plane.
- Use a 16-pin power connector so that 5V is available for DC offset calibration. Put an easily-broken trace from 5V to each CV input. Add test points for ground and the VCA outputs. This will help people perform the calibration.

Excellent seller. Great communication. Very fast shipping

Everything as described. Documentation was great, making the build super easy. All appears to be working beautifully. Already a repeat buyer

Easy build

Fun and easy build! I have 3 PM foundations modules I built from kits and they all worked first try. Fast shipping too

Versatile value

I got the PCB and face plate kit, and ended up ordering the components myself. This was a nice intro to DIY Eurorack.
I like the layout, and this module packs a lot of value at having two VCAs for the price of one. The assembly was straightforward, although the DIY kit implies that you already have the equipment needed to solder/test/calibrate your module. I would not advise this unless you already have some basic electronics skills.
The VCA is easy to use and is versatile in function. It goes well with the other modules I've put together from PMFoundations.

I have two of these now. They're easy and fun kits to build

I have two of these units now and after doing the calibration setup they work great! They're pretty fast acting and can work well for percussion, although most of my stuff isn't percussive. I'd recommend these kits to anyone who is interested in DIY modular but not real familiar with soldering. Just make sure you take your time and follow the directions carefully.

Highly recommend

First thing I have ordered from Tindie. The seller answered all my questions and sent the order within a day. Items arrived quickly without any problems. Both the boards and panels look good quality but I am yet to put them together as I am waiting on parts.
All in all very happy.

Great product

This Dual VCA was a fun build with easy to follow instructions. It worked great with no problems. If I was building a bigger eurorack, I wouldn't hesitate to buy and build another one of these modules.

Awesome, compact, DUAL!!!

This VCA, as all modules from PMFoundations, is of incredible use, and comes in such a tiny package! Great PCB and panel layout and excellent build documentation. I will definitely be doing business with PMFoundations again in the future.

Nice sounding and compact VCA, piece a cake to build.

This was my first module to build and it was pretty much dead simple to build. I definitely recommend this module for first time builders to start, also sweet to have dc and ac input

Great VCA

I really like this VCA. Easy to source and build, sounds good to me and doesn't take much space. I'll probably end up with a few of these.

Great module, great service!

I am not very experienced at soldering, and when I first started building this module I had a bit of trouble making solid connections as the pads are pretty tiny. I emailed the vendor for some advice, and I must say he was brilliant! Lots of help and suggestions, very quick to reply. It turned out that the pencil-tip on my soldering iron was not the best thing to use - you need a screwdriver-tip or a chisel-tip, things are much easier then.

The build document is probably the best I have seen (in my limited experience) - very full descriptions and useful photos. It would be difficult to go wrong I would say!

Testing and calibration are easy and the module itself works very well, and it has some unusual features. I personally really like the look of the panel too.

Overall, very happy and would recommend - will be looking at other modules in the range.

Finished two VCAs

Fairly easy build and great communication from the vendor. He helped me with some mods that worked out great and I'm using the two VCAs in my rack right now. The VCO is on the bench and almost ready for testing too.
