SAFETY INFORMATION Warning Caution Leakage/Resistance Check Critical Components List of Safety Components Requiring Exact Replacements DBR Bridge diode. Use only factory replacement. C1, 2 C6 Faceplate Air leak cover CMC1 L1 Fuse PCB Main PCB Faceplate. Use only factory replacement 10uF 50V electrolytic redial See Page 16 Service Bulletin SB2AMI Power output module. Use only factory replacement 4700uF,50V electrolytic filter caps. Be sure replacement part is at least the same working voltage and capacitance rating. Also the lead spacing is important. Incorrect spacing may cause premature failure due to internal cabinet pressure and vibration. 2 Amplifier/Subwoofer PSW-D110/DPS-10 F1 PWRCORD TRX1 Transformer. Use only factory replacement. SPT-2 or better with polarized plug, UL approved wire with the hot side to fused side. Use with factory replacement panel strain relief only.
