I'll post some voltages and links soon for a debugging
Thanks
Struggling with a new tablet !!!!!!!!!!

substitutions
9.1v zener in place of rd11eb 11v zener

had some trouble for a star when I burnt out the TL022 with a solder bridge.
debugged that swapped the tl022 but i get no chorus at all ,none of the pots have any effect that i can hear.
it just sound like a buffer.
i havent tried replacing the mn 3007 chip or the mn3101

i found a few errors in soldering around the power supply that ive corrected since taking the above pics
the voltages where taken after the corrections

i built the tonepad small clone and am quite content with it but i thought id try the ce2 because i thought it sounded brighter and more present on the demo videos i saw.

I'll bet you're standing by with that audio probe, Rich, but I'll suggest it anyway!  Sounds like IC1 is OK, since the "buffer" works (and your LFO is wobbling).  But are you getting signal going in and coming out of the MN3007?  Dare I ask where the 3007 is from?

If it helps I can get the voltages from my working tonepad ce2 when I get home from work tonight. I also have a few more 3007s if that's what it turns out to be.

Got it. i made a mistake on the output of the mn3007 all corrected and working thanks guys
Now for the mods. then i can get working on my Mutron iii.
thats a relief

I like the intensity and vibrato mods. I didnt bother with the effect level mod yet although i might later and maybe make it rack mount.

I like the effect level mod, more so than the intensity and vibrato. I'd probably just do the effect level one in a future build.
