Do the 600s work well?  If so, there is nothing wrong with using a pair 
of them with dividers and combiners. It's a very good way to double the 
power.  Put 4 together and run them conservatively.  It might improve 
the IM.  OTOH that's a lot of current out of a PS.

Most higher powered SS amps are 2 or 4 individual PP amps/sections tied 
together with combiners.  It works well with 2-meter amps  There used to 
be one that had 4 sections and ran 600 watts. I had one for a while. The 
original owner talked me into selling it back to him.  At times I wish 
I'd kept it.

You can do the same with 2-meter amps. Just disable the keying in one 
and let the remaining one key both.  You do have to keep the phasing 
such that the signal from one doesn't get back into the input of the 
other and you end up with a high powered flip flop and the amps have to 
be identical for the simplest setup.
