Congrats on the purchase of 802Gs !

Don't beat yourself up on that, afterall, 6.8R (fairly common shorthand ) looks very similar to 6.8K .
Just a note of caution ( since you are playing about with tube amps ), it is worth double/triple checking everything .
The bad news is my new 802-8Gs should be here tomorrow too. Do I install them too while the back is off or exercise patience and wait for the new mic to arrive?
I fail to see the downside ( to that equation ) , I would install them and get on with enjoying them .
I was keen ( somewhat ) to see what the 30923 network could do for your 806s / but that can wait for some other opportunity .
I think I'll take Earls suggestion and rebuild the XOs without the L-pads. After all, what are the chances that I'll need to mitigate the highs?
As long as you do include some form of midrange reduction ( then running without the existing variable Lpad, is worth trying out ).
- Note, your existing variable Lpad once freed up for other uses ( one side of it > usually the 0-30R portion ) can be wired into the 30923 circuit in place of the 6.5R resistor. Doing this ( along with a small "stop-limit" resistor of say 2-3R ) simulates the same ( variable ) midrange reduction circuit, as found in the N1201-8A .
And FWIW, the Samson Go Mic supposedly goes from 20Hz to 18K and REW is definitely set to start at zero Hz.
Once you have your new test mic ( & load it's EQ correction file into REW ), you'll be able to determine just how linear ( or not ) your Samson mic actually is ( through some direct comparisons of the test subject ) .
