||Vactrol Replacement for DOD 440|
I've built the Guitareffects..... DOD 440 Envelope Filter.. but i just hear a quite distorted guitar signal with no ENVELOPE MODULATION.. Diodes are right, caps and circuit traces of the board too.. but i've desoldered an old vactrol VTLC5 /??? optocoupler (from a compressor stage of and old fender bassman compact) that has the same pins compared to the one in the Layout at Guitar Effects....
I've replaced it with a diode and a center tapped LDR and the LED doesn't work..
