Read the attached article . Note the section on "Source Follower Drive for Output Tubes" A MOSFET source follower flat out works and drives A2 better than anything else.
Read this one too http://tubelab.com/designs/845-se/
The Shishido amps are also an option, but I could never get the designs to flow much current into the A2 grid: http://www.single-ended.com/direct811.htm
