I have a TL-922A and I run a TS-2000 into on AM - all knobs to the right 
on 40M!

I'm not joking at all!  Power - full.  Mic gain - full. Processor - on.

Say what you like, but on the air it sounds fantastic, as long as you 
don't yell into it or else it gets a little overbearing, but never an 
ounce of splatter.  I also use the DSP modifier, and I get all sorts of 
comments about my whopper AM signal.

The amp runs in SSB mode (full HT) and the tubes run just-glowing, like 
they would be on SSB with 100W drive.  I can key down as long as I like, 
and the amp sits on about 400W carrier and PEP is god knows what, but 
the power meter is swinging pretty hard on voice peaks.

Using a Tube Amp on AM is totally a blast!
