I did try it but not really working... Needed to boost signal at input and oscillation is really not stable...
"Eddit", wen I added the 4 missing resistors, work like a charm, not the most powerful phaser vibrato but very pleasant. I had great results with NSL32 optocouplers. but I will try LED/LDR tomorrow again, I tried some today but background noise was BIG...

Update on built:
1 the best is to use only one lamp for all 3 LDRs à la Univibe.
2 USE trimpot in series with resistor (82R) on darlington who drives lamp effect is very sensitive to lamp brightness
3 40408 can be replaced by BC141
4 I used BC108B from CDIL
