3904 & 3906 work fine in the Small Clone.

With those vales, you'll change the frequencies of the filters, so you could end up with a darker pedal or one that lets clock noise through, probably be fine though.

Those 3007s... you tested them in a working pedal? All the same date code  :-\

That's what I found questionable... they could all be from the same batch of course, or they could also be from the same faking stamp...

I'm just short of the 33nf. Everything else is on the board already ;D

My Zombie is good to go as soon as I've wired up pots and jacks.

2 & 6 of the 3007 should have approximatley half voltage, what are there voltages without the 3007 in there?

Pin 2 drops to 0 after a while but goes back to close to 9 if I poke around a bit on the other pins.

Found that my layout shows pin 3 of the 4046 connected to pin 6 of the 3007. The schematic has pins 3 & 4 of the 4046 connected to pin 6 of the 3007.

I'll correct that and report back.

Sadly this is a day of planned activities as well as work. After work I have three meetings/activities to attend before I can get some DIY time.

Just looked and the 33nf cap I'm missing to complete my Small Clone is the input cap, guess I'll be ok with a 47nf there  ::)

I'll try that too tonight. Or more likely tomorrow night, will have to clear out everything on our balcony tonight (after the meetup with my sons new preschool class, a picnic with daycare, and an information meeting about renovations to our housing cooperative, did I mention I'm at work?) so the contractor that'll change the windows can dump the new ones there tomorrow morning.
