Clarinot Env Control Circuit Daughterboard (Schem & Vero)
Posted: 25 Jul 2019, 20:34
I'm a big fan of Doug Deeper's Mid-Fi Electronics stuff. Especially the amazing Clari(not), for which I've owned production versions as well as making a few of them myself. His envelope control circuit is so simple, yet can make sounds that range anywhere from spastic brain-hemorrhaging space farts to subtle, dynamically controlled tape wobble.
I've been building some other PT2399 delays and have noticed how different some of the filtering, buffering, and feedback sections of the circuit can be from project to project. I thought it would be cool to have a daughterboard module that could easily add the Clari(not)'s envelope control to other delays to see how it would fit on other "HiFi" or tape-voiced delay circuits.
This is probably my 2nd or 3rd ever vero layout from a schematic, so I basically have no idea what I'm doing But I wanted to see if y'all could spot any errors or help me improve the schematic or layout before I start building a few of them up:
Schematic:
Veroboard Layout:
Link to album if these don't show up right:
Another envelope controlled delay that caught my ear is the Snazzy FX Wow & Flutter. And although it isn't completely traced, I did find a schematic by u/raindog in another thread, but it didn't look like anybody had built it or verified it. I adapted to a more readable format with the hopes of turning it into a daughterboard as well:

My Schematic:
I have a basic understanding of the Clari(not)'s vactrol and how it can be used to control pin 6 of the PT2399, but this circuit snippet uses part of an MC14007UBCP instead, which I don't really know anything about. I looked in some old school desk references like Hoebeek's Digital IC Equivalents & the Harris Semiconductors Integrated Circuits Data Book (from way back in 1975). They seem to equate the CD4007 & the MC14007 as Dual Complementary Pair Plus Inverters, but from different manufacturers. Would the CD4007 be a substitute in this application?
I may take a stab at a vero layout for the Wow & Flutter envelope control, so if anybody has tips on how to most efficiently lay out certain parts of the circuit, I'd really appreciate it!
