Hmmmm
The push/pull triode connected 42's w/fixed bias p to p load is 6K sez my '40 RCA tube manual and spec on the original transformer is 5.9K. With that in mind I would go w/ 1 and 3. Rca sez it will make abt 10watts @ 2% distortion. Wired as penodes they will abt twice the audio power but almost triple the distortion.
YMMV
When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
