Just dug out the relevant email from Ken, here's the excerpt, I was off by a few watts :)

Finally, I've just hooked the amp up to my signal generator and oscilloscope, to check that she's throwing the right shapes and to measure what kind of power she's able to put out. The shapes are good - nothing ugly or horribly unbalanced and no sign of parasitic oscillation - and the figures tot up as follows:

VA350 working into a 4 Ohm dummy load.

1kHz Sine wave injected into the Line Input and the signal generator's amplitude increased until the VA350 reaches the threshold of clipping.

At this point, the RMS AC Voltage at speaker output was measured as 39.6

Power calculation goes as follows:

39.6 squared = 1568.16

1568.16 divided by the 4 Ohms of the dummy load = 392.04 Watts

Loud enough for you? ;-)

Cheers,
Ken
