     In the ASM-1 VCO:
     
     Source = goes towards CA3140 (-) input
     Drain  = goes towards CA3140 output
     Gate   = comes from LM311 output

 Hi people of the list,
     
 I bought some 2N 4391 jfets from Mouser for the ASM 1 board, but I'm not sure
what the pinouts are on these guys. I'm guessing that the lead closest to the 
little tab that sticks out on the can is the source, the middle lead is the 
drain and the far one the gate. Anyone know for sure ?
