Also: Pictures are working now, looks good! Those filter caps are a little hilariously big, lol. And I love the rainbow knobs on the other synth! Reminds me of the original C64 marketing logos. I wanted to do something similar, but it’s relegated to just the feedback knobs around back.

I had originally planned on a standard barrel jack for power. I ended up going with the 7-pin DIN for a few reasons. Probably the main reason is that the header pads for a panel-mounted power jack are close enough to the edge of the board that they kind of interfere with placing a panelmount jack at the same location. You might be able to get around this by placing the jack higher up on the rear panel or elsewhere on the panel altogether, by using angled headers instead of straight, or by simply wiring the jack directly to the board (though this list option will make servicing in the future more difficult). The above hurdle could have probably been surmounted, but lo and behold, a 7-pin DIN connector randomly fell into my lap. I had been asking around for a source on the OG power switch, and a kind forum member hacked off a piece of original C64 PCB for me that contained both the DIN jack and the switch. Obviously this won’t be the case for y’all, but having the part in hand made the decision a bit tougher. Other, minor reasons I went with the DIN jack: no need to redesign that part of the panel (I had custom panels made but I didn’t want to change any more than I had to), and no possibility of using the wrong voltage/polarity power adapter ever. Attaching the new jack to a power adapter was really easy; don’t let that be the only reason you shy away from the DIN connector. That all said, if the part hadn’t magically appeared for me like that, I’d have probably figured out how to use a barrel jack. I’m afraid I can’t advise on how to adapt the DIN sized hole to a barrel jack though, that’s a tough one. I had planned on custom panels from the beginning.
