Grant, I also have a trio of Tungram 12AU7/ECC82... not only are they very similar in tone to Mullard - they ARE Mullards - manufactured in the Blackburn factory and labeled Tungsram!

Wow! Never heard of that. Good going, Joe. Mine are not manufactured by Mullard as far as I can tell. New production East European variety. But, they still have a Mullard-esque sound.
