(...) Well, just off the top of my head, when you say "get 16 vac out" how are you determining this, a volt meter set for "Volts AC" or some such? Not, say, an oscilloscope? You will note that almost all meters render "AC Voltage" as the RMS (Root (...) (26 years ago, 30-Jan-99, to lugnet.robotics.handyboard)
