OK :)

While that's a good idea, I'm not on that list. I asked you about it
here because you actually built one, and DIY modules in MOTM format
seem to be one of the subjects of this list.

I would be interested in hearing that.

That makes sense, although I am also interested in how well it works
as a VCA. Which is perhaps why I asked a bunch of technical questions about
bias voltages and suppression grids :)
Thanks again for your input.
