SV: [sdiy] Hammond Transformer Question

[Karl Ekdahl]

Romeo,

You don't state which transformer you have of these, but from the datasheet i'll have to assume it's a 185C36, 185D36, 185E36, 185F36 or or 185G36. What you want to do is to use the Series configuration, and use both pins 8 and 11 as your center-tap (ground point).

Karl
