Didn't they change the suffix on the 3CX1200 to something new?

## Just look it up on eimacs site... or better yet, look it up in the eimac catalog.
They make THREE  different versions of the tube...and still do ! 
A7, D7, Z7.     The Z7 is the best of the bunch.. and  has the lowest feedback C...
and no socket  required.   It has a grid flange.
