Spencer,
please check the simplified
DC schematics. For DC cathode of D110 and cathode of D113 are connected. Both DC voltages must be equal. Something is wrong here. Regarding schematics Q511 drain voltage is eaqual to cathode voltage of D110 and D113. For D110 it's ok but not for D113. So D113 is not right connected. Please read the linked
Wiki page for some debugging to find the issue. At first you should check continuity between K of D110 and K of D113 (see No 1 Wiki page).
