I'm just referencing the pcb to see which are polarized or not, and also checking some of the photos at the beginning of this thread. There's 3 styrene caps, one should've came with the kit, the other two I ordered from Banzai, along with the 2sk117.

Is C10 a standard electrolytic cap? I'm not sure what "Elna" means, maybe the brand?
Elna is indeed a capacitor manufacturer. The "pattern" in the BOM file says "CE" for it, which most likely stands for "Capacitor, Electrolytic". Not that the round footprint isn't a dead giveaway anyway...

Ok, I figured that I should double check just in case. Thanks

another question to the parts list 
which variant of the BC550 and BC560 is recommended. And the C4 (0.1/100)is which "unit" uF or pF?

0.1/100 = 0.1uF (100nF) rated at 100v
