Sorry I did edit my message too from it’s initial state!
I love your passive box design I think these types of utilities are criminally unavailable, especially for the tabletop synth/noisemaker musician.
I will flag that OSH are not the cheapest option, but they are excellent quality and have good tooling. (When I say ‘not the cheapest option’ - three boards for the
16n thing we’re building work out around $250 with OSH, and I can get five for $50 from my preferred decent-quality Chinese supplier.)
Of course, your attitudes towards eg shipping, air fuel, etc, may - and should - inform your PCB supplier.
I very much like that it’s lots of small separate boards - if only to make it a plug/play toolbox of components!
Yes I agree on OSH park costs, but I don’t know of an easier way to make boards easily available for anyone to order.
I can also upload the eagle files so people can have them made by their fab of choice.
Last night I revised all the modules to be under 19mm in width (max). That way people could also fit them on a 4hp panel if rack mounting is preferable (plus gives another use for any spare boards left over).
Thanks for all the positive comments so far
I had a bit of time last night, so I’ve tweaked the layout, added the features discussed, and also added a new PCB for a half wave rectifier.
I’ve collated the schematics (see attached .pdf) and would greatly appreciate it if someone could have a look just to double check everything is in order

In terms of panel/box layouts here is what I have (checked with PCB and enclosure dimensions):
The 1590B is using what I will have left from 1 OSH park order for a full set of boards.
In terms of group buys, I’ll upload all the Eagle Files here, so if someone wanted to organise a group buy and get boards fabbed…no problem
um yes please thanks
