[Hallicrafters] Matching Speaker Impedances in R-46 etc

[Craig Roberts]

Hammond makes a nice, clean sounding 600:4/8 ohm audio transformer. It's 
available from Antique Electronic Supply (www.tubesandmore.com) for 
$18.60.  It's catalog number P-T119DA.  It works just fine for 500 ohm 
inputs and 3.2 ohm speakers, too.

I've used several, including one in a rebuild of my Hallicrafters R-42 
Reproducer and one for the output of my Hammarlund SP-600. 

73,
