Hello, I am working on a kenrich eagle 200 that a buddy gave me that needs some help, the only schematic that I have from a member on here I believe is fairly blurry and I was wondering if anyone could tell me the value of the resistor at R11 ? Also possibly if there is a diode at D9 ? Is it supposed to be a 171 and if there was supposed to be a cap at C4 ? It appears like there wasn't ever one there possibly. Thank you all
