Hi everyone. I did a search through the archives and found that some have built 
the revised version of the bob beck zapper. The new version no longer uses a 
relay, instead it uses an lm386 op amp. On the schematic it looks as though 
there are two op amps and not one, yet in the parts list there is only one op 
amp required. Can anyone help. I think it might be just one op amp but it has 
been divided into two to make drawing the schematic easier. Im getting the 
parts tommorow and cant wait to try it. Thanks for your help
