[Amps] QEX Innovative Tube Linear?

[zdtech]

Hi Dick

Most interesting, i just wonder how they went about improving the 
terrible IMD from Sweep tubes? It would  be great if the same technique 
could be used with some better quality transmitting tubes.  What 
magnitude of improvement in 3rd order IMD could the author of the 
article achieve? I look forward to reading about it.
