I almost have this build memorized. This is my third Better(not), a modified Mid-Fi Clarinot. I'm running low on 5mm red LED, so I tried a pink one in the vactrol. The attack and release was faster and less predictable on the modulation. Unpleasant, really.
I ran out of skinny and tall electrolytic caps, so I used fat and short Panasonic caps. I love those things, but I should have added a couple rows on the vero to accommodate their width.
