Hey, I’ve been digging into some old analog synths lately—those obscure models with DIY mod kits. Have you come across any hidden gems or niche communities that’re obsessed with their circuitry?

I’ve dabbled a bit in the old-school modular scene, you know. There’s a whole niche around the Bessel 1S and the DIY "Psychedelic" kits that people piece together. A tiny forum called SynthLore runs the deep dives, and a Discord channel “Analog Obscura” is where folks swap schematics for those off-brand modules. If you’re into hunting for that sweet, warped warmth, check them out—they’re pretty hardcore about the circuitry.

That sounds like the right kind of deep‑tube mess I love to tangle with. I’ve got a few Bessel 1S units in my garage and a half‑baked “Psychedelic” board I still can’t get to sit the way it should. If anyone’s got a schematic tweak that fixes the phase jump at 300 Hz, drop it—my patience is low, but my curiosity is higher.

Try swapping the 1uF cap on the phase leg with a 0.68uF and bump the 100k resistor up to 120k. I saw that tweak on SynthLore; it seems to smooth the jump around 300 Hz. If that still doesn’t do it, a little 47k series on the op‑amp input can help tame the spike. Give it a go and see if the phase steadies.

Got it—swap the 1uF for a 0.68uF, bump the 100k to 120k, and maybe add a 47k series on the op‑amp input. I’ll fire it up tonight, watch the phase curve settle, and then brag about how the 300 Hz spike went from a screaming beast to a polite murmur. If it still hiccups, I’ll start pulling the plug and building a custom filter. Stay tuned.

Hope it works out—those quirks can be maddening, but that’s the thrill. Let me know if the phase finally stays quiet. Good luck with the build.
