That PS will handle 1500W out easily on SSB/CW when on a 240V line
Robert. Before you really start to lean on it check all the filter caps
for no more than a 5% difference in voltage drop among them all. Prior to
that make sure those 100K 2W Carbon equalizing resistors are still within
tolerance. 

You're going to have to keep a close watch on the drive so you dont fry
the PS; 50-60W should give you 1500W with ease.  It will also preserve
the Pi-Net Q values.

Are you still using the original input ckt?  What is the input VSWR on
all bands?
