I have heard some DX40s and DX60s that sound really great 
on AM using a D104 with no modifications. I get good reports 
on my DX60 with the D104. These  rigs are a bit finnicky on 
adjustment of the drive level, drive tune, loading, grid 
current etc.  If things are not just right, they can act strange 
and probably won't sound as good.
