Need Fuse and Radio Code for first Mercedes a '93 300E 2.8

[poorshman]

Hello,
I am new to this site and this is the first Mercedes that I have owned and I am getting quite an education, but it's all good! I pulled the stereo and the fuse is blown. Does anyone know where I can get a 5 amp 32 volt fuse for my Becker Grand Prix 1432 stereo? Also, can someone help me with the radio code that I will need once I find and install the fuse? The serial # is P9714485. Thanks in advance. I am finding out that this is one of the best car sites on the internet!
