I'd leave the 78 and the 6K8 alone as they may not be too compatible with the 6D6 and 6A8. The 6D6's inter electrode capacitance is is different so they don't like to play nice when swapped for 78's. The 6K8 is different type of mixer tube, triode/hexode which is different from the pentagrid converter that the 6A8 is.
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.

Now I think I've got it!
