See attached article for a cathode follower driver for 810 triodes.

Steve, that is an excellent reference.  I used a similar technique for driving a quad of 1625s in AB2, but used RC coupled audio amplifiers and a phase inverter instead of the driver transformer.  The results are stellar!  Thank you for your post!

Link to my project which shows a very similar technique with the 6SN7 cathode follower:
