Been away from the forum for a while but I saw this and it looked interesting enough for me to build up tonight. Great layout! Just a few things to get it sounding like the demos.

- Like Ciaran mentioned, move width 3 to their other end of the 510r resistor.

- Move the bottom of the 33k resistor up to pin 6 on the pt2399.

- Remove the cut between the 2n2 cap and the 10k resistor (next to pin14 of the pt2399).

I did these, and it sounds like the video posted in the diysb link. Really digging this circuit, thanks again for posting!

Does anyone know how I could get an even slower speed from the speed pot? My guesses would be changing the pot's resistance or messing with the values of the caps surrounding the 358. Am I off base or are one of those a step in the right direction?
