[Amps] 3-400Z Tube Replacement ideas

>How about a 3CX1200?  

The new 1200Z7  is less squirrelly than the old A7 version, but the 
filament V & I needed is higher than a 3-500V.

>There are many articles about converting 3-500 based

The 8877 has a 5v heater, the same anode V-rating, c. the same drive 
requirement, but about 40% of the input Z. At the Rx end, it would do 
about half of a std 6db S-unit mo' betta.
