A couple of quick Dark Rift Delay Questions

I'm getting ready to build a couple of Dark Rift Delays - is this fix still needed or has the board been updated?

Space Spiral:
Remove C30.
Connect a 10nF cap between pins 6 and 7 on IC5. A small MLCC on the back side is a clean way to do it.

Looking at the current build instructions schematic, it looks like C30 is now a 10nF between pins 6 and 7...

Also, on the LM324 chip - I don't have any "A" models handy, but I do have an "N" - can't seem to find an "A" - thoughts?
 
Nope, that modification was made a couple years ago.

Unless you have a really old PCB you should be good to go with no modifications necessary.

The back of your PCB should be marked "Rev 1.3" under the "PCB285" identifier in the bottom right corner.

Yep - I've got a 1.3. Thanks! :D

What about the LM324A vs. LM324N?

Anything I need to worry about on the I/O wires (shielded, non-shielded)?
