From the post
Got a bunch of CD4049UBE chips left over from building Red Llamas? Here's something else you can do with them. You might need to play with the the value of the 8.2k resistor going to the drain of the J201 to make sure you're getting to around 4.5v there. Also if you encounter squealing or unwanted noise, try increasing the power filter cap from 47µ up to 100-220µ. Sound clip and schematic can be found here.
