#107 done!
i popped in the new ba6110 and it works! i had been using it straight from the vcf output for kicks, but it sounds much more wicked with the vca, beyond what i expected.
i sorted through 100 733s from mouser, plus the ones from the kit, but the highest reading i got was 305 (maybe it's the meter?). the resonance definitely sounds as pronounced as the 303s i've used. the square may have slightly more harmonics, i'm not sure. it sounds wonderful though.
i did the envelope range mod and the power supply mod. i didn't really notice any significant "warble" until i got near 1k of resistance; this actually sounded like a ~ 10hz filter modulation. i don't know if i could really tell the difference at 220 ohms, but i put it in for good measure. i may extend the envelope range (max and min) and depth, and maybe a decay pot for the vca?
a couple of quirks: 2 of the buttons ended up a bit lower than the others, but they all still work fine. i'll have to take the panel back off and investigate. also, my step leds work great while it's running, but inconsistently turn off when i'm editing in step mode. should the current step led stay lit until the pattern is advanced? sometimes they do, sometimes they don't.
now, to learn me some C! what i'd like to add: shuffle, pattern shift, momentary R A S action, midi sync in write mode, what else?
oh, something i hadn't anticipated in play mode is if you press slide, then rest, it holds the current note until the vca dies or rest and slide are pressed again, cool!
