Hey Ron,
Just for grins you might want to try a 6SB7 in place of the 6A7. You will have to make up an adapter but it has twice the conversion gain of the 6A7. The grid configuration is a bit different than the 6A7 but can be wired up to work. I think I'm going to give it a try in the 37-620. Should really give the SW bands a boost.

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!
