      It will work fine.  The headphones are driven off one plate of the 
phase inverter.   In fact, pulling the output tubes and using phones was 
one recommendation when running on batteries to save power.

I recently did that with a Patterson PR-12 and it worked out very nicely. I doubt that I'll get lucky enough to find the proper National speaker at any hamfests this year.
