Muffin Factory Input Resistors and other build information

[halffast]

Muffin Factory interstage coupling caps......
Options are 100n fixed and 22n switchable so a choice of 100n or 122n.
Seems like a smallish differential?
I'm thinking keeping the 100n fixed and using something like 680n switchable?
Thoughts? Since many of you have much more experience with Big Muffs and clones.

Excellent work Feline! Tks. You're a lot quicker at doing this type stuff.

NOT quicker, I've just been thinking about all this stuff for a long, long while...

Gathering bits of info, ruminating, wondering, questioning, investigating, scheming, dreaming ... for years now.

Am I correct in stating that the two collector to base resistors (indicated with red arrows) in the Muffin Factory screenshot below are to bias the two germanium transistors? And that their values were selected primarily to bias the two Ge transistors?
