But if you don't mind having a tombstone the early '36 116B is the one to get. The 10 1/2" H spkr can handle the 10w output stage a little better that the 8" K spkr. It looks like the design is a work in progress on the 16B code 121 ('33 cathedral) as there a lot of updates in the service notes. The later runs of the 16B and the 116B have a much more effective tone control circuit than the code 121 (the '33 cathedral) pretty much just cuts the high frequency response from the audio.
On the rf/if side of things the later runs have a rf amp where the code 121 has the qave circuit. The alignment on the later runs is more straight forward and helps to make the set more accurate.
GL on your search!

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!
