[sdiy] V33XX vs AS33XX?

[rsdio at audiobanshee.com]

We’ve been discussing the sorts of new projects that would be worthy of these reissued parts, as opposed to mere reproductions of old designs. Perhaps the best new project would be a socketed evaluation board for each type - x3320, x3340, etc - such that these comparisons can be made as a start on answering these questions. Hopefully, the evaluation board design would have jumpers or other means of trying the most common circuit variations, since a single circuit might not be enough to fully evaluate each chip.

Such evaluation boards might even double as simple Euro rack modules for basic VCO and VCF kits.

If my Pro-One had the CEM3320 socketed, I’d have swapped them over to listen for differences…similarly with AS3310 and AS3340. But no banana, unfortunately - the chips are soldered on the Pro-One.
