[NJARC] atwater kent speaker impedence

[Al Klase]

Joe,

 From the tube data sheet we can see that the specified load resistance 
for the 71A is in the neighborhood of 4000 ohms.
(Drawing from: http://www.mif.pg.gda.pl/homepages/frank/vs.html Book 
mark it!  It's easier than getting up to get a book off the shelf.)



For your purposes, a speaker and output transformer from an All-American 
Five will work just fine.  The transformer primary will be more like 
10,000 ohms, but impedance matching is like horse shoes and hand grenades.
