My 2 B is SN. 9200 and it uses 8BN8¡¯s
Bill,
You are absolutely right!?? I screwed up! (That never happens does it?)
I see what I did now!!? Late last night I had both schematics on my desktop....? the 2-B? was a DJVU file and the 2-A has both.?? My browser will directly open the PDF but not the DJVU.? I have to save it first! (and I "saved-as" the 2-B as? 2A.djvu!!)
The 2-A of course, uses a 6AV6 driving the 6AQ5 audio amp and the 2-B uses the 6BN8 (triode section) to drive the 6AQ5.
Drake was clearly trying to save pennies and keep the tube count down and used the tri-section 8BN8 and/or 6BN8
Then they really reduced it in the 2-C
That 2A schematic from Bama was particularly bad resolution.....
