These new model MD-SR505E/70H/70W have almost the same structure as the former model MD-SR50H(S) except for some outer parts, the colour of the main unit has changed from black to champangne green, and so only these parts are here described. When servicing the MD-SR505E/70H/70W, please refer to the already issued service manual for MD-SR50H/ 50W/60E/60W(S2006MDSR50H/) as well as this service manual.
