[sdiy] Ray Wilson Envelope Generator

[Jim Bob]

Has anyone built the Ray Wilson ADSR?  I  built two of them.  One works fine, but the other does not  work.  Two of the IC's get hot when it has power.  I have  checkd every solder point.  I have checked every component  value.  I have checked the polarity on everything.  I have  checked that all of the diodes are ok.  I removed all of the IC's,  put in IC Sockets and installed all new IC's.  I still have the  exact same problem!
  I can't think of anything else to try.   I am about to give up,
  If anyone has built it and knows a little more about electronics than  I, maybe you could think of a reason IC's U3 (cd40106) and U4 (cd4066)  are getting hot.  Any advice would be greatly appreciated.
