I run an AL-811H at 800 watts even on RTTY. It holds up real well. I did the 
stability mod (http://www.w8ji.com/al811_important_modifications_changes.htm) 
on it after burning up the grid resistors - they really burned on 10 meters 
and I had to air out the shack before continuing operating. I replaced the 
original tubes mainly because I lost 2 of them but also because the original 
tubes were made in China.  Replacement tubes I used are here: 
http://www.rfparts.com/811amq-sel.html. The AL-811H has been very reliable 
using the Taylor tubes with the mod.
