Is there a typo in the schematic, or is it just my ignorance showing early in the morning?
The cap to the left of 4N37 is labeled 10K. Should that be a 10K resistor? Or is it 10uF cap? I notice one of the two 10uF caps on the right is listed as 10K as well.

No typo as far as I know. The cap to the left of the 4N37 is labeled 1K (1000uF) and the cap at the speaker output is labeled 10K (10,000uF).
I have built this circuit with those values and it works and it sounds great. Not with 2SK77B of course, but with THF-51S.

Thanks for the clarification you guys!!!
@Ben Mah, did you build the THF-51S version point to point or did you design a circuit board?

It's point to point. See 50w Single-Ended BAF2015 Schade Enabled (post #857) and 50w Single-Ended BAF2015 Schade Enabled (post #905).
Now Zen Mod has a pair...
Fantastic + 1 pair with Michael Rotacher it's a diamond's gift
well , in this moment it seems it'll be either slightly Babelfished iteration of what you did show in BAF 2015 lecture ( with input buffer implemented in biasing, servo - still thinking about) , or it'll be some big bstrd with inductive load
however , no hurry ....... pleasure is in entire glass of wine , not just final felling in da belly
