[NJARC] inconsistent tube types

[Al Klase]

Paul,

That can only be a typo.  35W4 is the 7-pin miniature version of the 
35Z5 rectifier.  50L6 is the proper output tube for a typical "octal"  
"All-American Five".  The rest of the line-up is most likely 12SA7 
converter, 12SK7 IF amp, and 12SQ7 detector/first audio.

Data on this and many other sets is available at:  
http://www.nostalgiaair.org/ in the "resources" section.

Regards,
Al
