I don't know how to read resistors, so I'll take another pic. I don't see R1 on the photo - just R2 and R3 are circled.
BTW, you can't see it in the pics, but on the bottom right, there is a small green 102K cap to the right of the big green 474K.
I listed that in my values, but wasn't sure if you caught that.

Here's some better pics of R1 (I see it circled now )
I don't know if you noticed, but C9, C10 and C11are all orange 47K 1kv caps

Oh yeah, in answer to a PM, this thing thumps fast or slow according to the rate pot and it does do the phase thing at the same time. It sounds really good actually! Now, If I can just get rid of the damn thumping.......

Try putting a 470uf across the +/- of the power supply.
This usually helps with "ticking" but it may solve what
you have as well. The Oscillator is usually a "thump"
sound so maybe the oscillator is bleeding into the audio path.

I don't see any markings on the sides ( I didn't remove them from the box though) They're CTS pots with 1980 and 81? dates. Rate is shown first and then intensity.

I would like to see one (ore more) picture(s) of the wiring first.
As you may have noted, my schematics always include the wiring too.
The pcb itself I have traced, but currently I am a bit confused, why the audio signal is fed to the LFO.

And yes, is the grren capacitor near the yellow wire really only 2n2 or is it maybe 22n ?

Here's some quick wiring shots. BTW, if the cap by the yellow wire is C3 - it's 222K. See my earlier post.
I'm not a DIY'er. I can wire pots and switches, but that's it. Maybe I could send it to one of you guys for fixing the thump? PM me, if you want to help me.
I've got an EH Bad Stone 1st version "mummy" that isn't working too. No sounds at all on that one. Thanks.
