[sdiy] rwilson sample hold HELP

[Jim Bob]

Ok.. so earlier I asked about the transistors in the sample hold I  built.  Someone said raidioshack had the correct ones, so I went,  and they did.
  I...
  Etched a new PCB.. checked it over very carefully
  soldered the parts on one at a time checking the connection and for any  stray solder traces.  (these are all new parts.. didn't take any  off the old board)
  Used the correct transistors
  
  I have the EXACT same problem!!  
  It is like the clock is not working, or something.  If I tap the  transistor leads it samples and holds.. each time I tap it, I get  another sample.   Anyone have any ideas?
  
  Has anyone else built this sample hold?  Anyone running off 15 volts?
