First off for those wanting a KPA-1500, might consider combining two
KPA-500 for 1000w (much easier and cheaper). Otherwise, it makes
more sense to design a new 1200w amp around the new LDMOS devices
($250 range). Designs are being done for 6m/2m/432 with the
Freescale LDMOS and some folks are starting to market them.
OK, 600 meters: I will assume the writer is not into building his own.
The easiest route to operating on the new 472-479 KHz ham band (not
approved until after Jan-1, 2013 by WRC), is to buy the KX3. We have
heard Wayne state it will be able to operate there. I can possible
satisfy the 100w goal as I may offer an 600m amplifier based on the
AN-762 kit from CCI. See my "kits by KL7UW" link.
I also show how one can make their own low-level transverter to take
the output of the K3 running in TEST mode on 10.472-10.479 MHz to 472-479 KHz:
http://www.kl7uw.com/600m.htmscroll down to the date tag: "March 17, 2011".
That will require building a couple amplifier stages to get to 1w
drive for a AN762:

I'd rather have the 100 Watt 600m transverter. ;-)
