| br>I just finished building up a ADSR/VCA. I'm not getting any output, and U2 is incredibly hot to the touch. All the other IC's are fine - and no magic smoke has been released.
Any suggestions on where to start? U2 calls for a 4052 DP4T analogue switch, and I have a CD74HC4052E chip in there.
UPDATE: Learned there is a difference between CD4052 chips and CD74HC4052 chips, notably the maximum voltage rating. That would explain the heat, and completely fixed the problem. br> br>
