Steve,
Those were rms figures of course; if you need peak values, multiply by 1.414

Firstly your figures are out for the 50 Ohm system; the figures are
273.9V and 5.5A
Once the SWR is no longer 1:1, there is an infinite range of
impedances for any particular SWR, and therefore an infinite range of
voltages and currents for a dissipation of 1500W. However, here are
the upper and lower limits:
2:1 SWR: 387.3V / 3.9A thru 193.6V / 7.7A
3:1 SWR: 474.3V / 3.2A thru 158.1V / 9.5A
