My oscilloscope says it's 320 V p-p. This means our output voltage is
	160 V	*	sin(	377	*	t	+ 	delta)
	1/2 of p-p		2 * Pi * 60 cycles		time offset

And, 160 * 2^1/2 = 113 Volts. OK? In a perfect 120 Volts RMS world, it would
be 339.4 Volts p0p. 

Are we all settled now? Thank you. We now return you to your regularly
scheduled newsgroup.
