Hi joe209-ga, The sine of 22 degrees is approximately 0.374607, which means that at 22 degrees, the voltage is 0.374607 of its maximum. The maximum will therefore be 63 volts divided by 0.374607, or 168.176 volts.

That would be 168 volts peak. The RMS voltage is .707 times the peak voltage you have a 118 volt AC signal there, standard line current in the US. Note that our standard 118 volt RMS signal is actually 336 volts peak to peak.
