Take your time and enjoy. My theory with a project like this is that I may never get another chance to do another one of these. It's not a race, I sometimes have to remind myself. It's better to do a job right the first time than to beat some imaginary clock. And while the rest of us may offer advice or cheer from the sidelines, you are the ultimate arbiter of what is "the right way."

I agree. I'm working on it about an hour or at most two a day.
More and I get eyestrain and overexcited.

This morning I went though the Sam's resistance to ground
chart. The vast majority of the numbers are well within tolerance,
most well within 10%, including most > 1Meg resistors.

This is good news.

This evening I will do the resistance to B+ part.

I noticed that Sam's has a 12AT7 on their topside tube chart in
a 7 pin socket! (Its really a 6AU6).

I still have not got a reply to where the Candohm is in the circuit,
and the nature of the 100 ohm resistors inside the chassis connected
directly across its parts. Are these R286 and R287 in Sam's?
The ".100" resistor in Sam's surely must be 100 ohms, otherwise there
would be nowhere near -30v on the bias supply, as there can't
possibly be 1.7A B+ current.
