Jim,

according to the 425 30 W drive gets me 900W out I have an extra pair 
of tubes that were tested as full output and I've seen no difference 
between the two pairs so I'm guessing on this amp 30W in = 900W out.

I have no Bird or better so watts out is something I can't 
definitively ascertain with what I have.

The output is nothing like my 77SX rendered but well, that's a 
different amp.
