The clean boost with some clipping was very boring, both from a sound and a circuit standpoint. This one isn't any better from a sound standpoint, but at least it's a bit more interesting. Instead of a boost pot and clipping diodes, this has a pot that affects the biasing of the input JFET, and a fixed 10x voltage boost with a final volume pot. End result: it also clips, but the clipping is based on how badly the input transistor is biased, so now you have a bit more control over the result. Useful? No. But I'm back to using discrete components, because the whole op-amp thing was just too boring. If I want to use pre-made circuits, I can do that on the MCU board, let's keep the analog boards discrete. That said, I've made the resistors and capacitors small, because I'll just use this one for the JLCPCB assembly testing. I did send off a copy of the MCU board too, which is probably completely stupid - the first PCBA board I do shouldn't have been that complex. But maybe it works (after I figure out the programming - even if the board is fine, I'll have to do the SW side too to even test it). Anyway, this one I can have assembled - and test - without then having to write any code for various i2s things that I have no idea about. Oh, and I still call this a "1590LB" boost board, even though I actually ended up deciding that I'll just 3D-print the enclosure. So it's not really a 1590LB, it's a 45x50mm board that I'll just print a custom enclosure for. I actually really liked how one of my test enclosures ended up looking, and not being limited to standard aluminum boxes is liberating. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
