MOTM

Seeing the blinky LED's on Robert Rich's MOTM-800's in the demo video, made me want 
these too on my 800's, and I found the mod for this on Stooge Moe's website. Before I start 
to buy parts etc, I'd like to know which dual opamp is best suited for this? I realize almost 
anything will do, but I want to make sure I get something decent enough not to cause 
problems or interference, noise, hiss etc.  

Cheers :-)
