Certainly not with a T-Bolt Jim as it would be way past the melt down point 
as an AM linear.  OTOH the Johnson Desk KW, Collins KW-1, any 1000W 
converted BC rig etc will easily run a 700-1000W carrier since that is what 
they were designed for and the BC gear started using negative peak clipping 
many decades ago.
