Default PSU2 and power transformer question.

I was playing around with the Duncan Amps PSU2 software and had a question on the power transformer part. It asks for volts in RMS and was wondering how do I calculate that value. Say I have a PT of 550VCT. This could also be expressed as 275-0-275. Do I use 550*.707 or 275*.707, or is 550 or 275 already spec'd in RMS. Or am I way off here? TIA...

Use 275 - it's already in RMS. And use the half-secondary reisistance, or average of the two halves, for transformer resistance,
