PT2399 Delay

Maker	DIY Synth Manila
Type	Lo-fi PT2399 delay with voltage controlled time and a feedback overdrive jumper
Mounting	Through-hole
Width	—
License	Proprietary (Licence marked "none yet" on this repo)
Difficulty	🌡️ Medium through-hole

Clone of Music Thing style BJT current source on PT2399 pin 6. Roughly 30 to 340 ms of delay. Two wet outputs plus a dry output, and an aux input normalled to wet out 2 so you can put external effects in the feedback loop. A jumper hard clips the feedback with 1N4148s.
