sorry, but I wasn't able to receive the synth-diy mails the last days.
If someone replied my penfold question, it would be nice to do this

Here the more detailed infos:

I found the schematic on:

and I have troubles with the Logarithmic Converter.

How do I wire it up with the other pcbs?
Is it useful the the two collectors of the CA3046 are connectd to 0V?
What's the reason for using that Log Conv?

Maybe someone has already built it? I'm glad of any answer.
