ooh. I ll need to check what I had where that 4.7R is...Im pretty sure I didnt use 4.7R

also, is that correct on the 1n914s?
thanks

Hi Ian,

that resistor should be  47R sorry about that mistake. Check it yourself here http://samengstrom.com/46436194/en/read/6_Band_Resistor_Color_Codes using colours: yellow-purple-black-gold-brown-red. There any 47R resitor metal film 1% will work fine.

Yes, those are 1N914 but you could use 1N4148 anyway, those are the same thing.

Diodes D1, D4 and D5 are all rectifiers, those could be 1N4001, all of them if you like but you can read there that those guys used 1N4001 for D1 and 1N4002 for D4 and D5.

I hope this time your pedal works fine!!

Cheers,

Ian, after you've tried so many optocouplers and led/cells without success, I have to ask you, did you measure the photocells ?
If not just unsold one leg and using your multimeter with LED on first and then with a piece of black tape (blocking light going to the cell) to read the blackout resistance of the cell, then I guess it will be easier to find wich optocoupler will suit.

cheers.

Newest thread I could find, sorry for the dredge.

Has anyone built a Wobulator from the MarkusW Wobulator v3 schematic?
