Hi Joseph,

You are correct. The schematic for the bucking transformer was pulled off an article posted on an electronics website to illustrate the concept – I had not noticed that the bucking action was indeed shown on the neutral line in this particular configuration. Interestingly, the notes on the schematic show that this was a feature of ‘Rev 3’ to that circuit, however there is no explanation as to why this was thought appropriate! Given that the bucking will only float the output neutral line 6 or 12 volts above the input neutral, I (personally) would not be too concerned in this application, however, I will publish an errata in the Fall 2015 Newsletter. Thanks for pointing this out.
