Hi! If anyone here has more experience in designing pcb boards, I could use a little help!
I'm trying to adapt the API 312 schematic on KiCad, but it's only my second pcb design, and by far the most complicated for me. I want it to fit in my 500 series rack, so I found the footprint for that on a Github page. I designed all the transformers/opamp footprints myself.
I wanted to make it as easy as possible for my first build, so I gave up on the 48v, phase flipping stuff, etc... I only put an impedance switch before the input transformer because it was easy enough (and very useful).
The gain pot won't be a resistor ladder. To simplify and cut the cost, I'll put a 1k Lin.
I didn't take much time thinking about dimensions (to make the potentiometer fit nicely in the rack). I'll simply wire it "by hand" if it doesn't fit. I'll also wire the switch like that.
Here are the original schematic and my work :
Any help is really appreciated, thanks !
