Yet another etched and stuffed board that I have no idea what it is.  The chip on the right is a PT2399, and the one on the left is a TL074.  The pot values are 500K and 100K.  I combed my hard-drive, looking for anything that might be 2399-related but to no avail.  Any ideas?

My dry, sweaty foot had become the source of one of the most disturbing cases of chemical-based crime within my home country.

Yep, before scrolling down, I was about to say it does indeed have a Holt-esque look about it!

Okay, I'm gonna write the name right on the board with a Sharpie right now, and avoid any future embarrassments.

Keep 'em coming, Mark.  It keeps us on our toes!   ;D

It's the age of the Etch 'n' Sketch brain, Mark, donchaknow. Pretty common phenomenon (don't ask me how I know).
