Mr Thomeeque I've made the EH3207 version and it's no work, I I've to desolder the 100nF caps for VCC filtering, resold the sockets of 4049 and 4013, re jumps all for best results; by the facts here are the photos, it is made with webcam sorry for that: :

My etching PCB (Iron method):

The face markers for the components in its side:

All the jumpers in the components side (there are too long):

The jumpers in the solder side (um mm perhaps a short circuit in it!):

The resistors solder in order, the trimmer 22K it's changed by a 25K; it will be?? how a 20K in it?? (I'm making the EH3007 version):

The caps also; I used tiny electro caps; 1u and 4u7 are tantalum; the rest are multilayer or Greene caps, the ceramic caps are for pf values:

And all the rest put together; I use a individual PCB for the pots:


Well I tried to solve were are the problems!!!!

I'm making the EH3007 version; I'm here with it; a new mask and a new PCB pots:


The jumpers are more shorter all in the components side:


All the caps in the components side:


There are some questions for the EM3007, I use a 20k trimmer for replace the 22K in the list; the layout of Jorge's FLANGER have a 10V zener, this modified layout have a 15V zener 5W (it is 0,5W???) ; I can use the trimmer substitution value of 20K?

and also the 10V 0,5W zener?

Excuse me man I know it is too much questions; thanks for the adaptation of this, and the time consumed for do my suggestion; your great man!!!
