I think I am going to get a Dynavector 10x5 to replace the Rega Elys cartridge on my P3. Reading the archives, I learned that I will need to purchase a 2mm spacer to use this cartridge with the RB-300 tonearm. I have a Shure stylus force guage. But that's it. What else do I need in order to install this cartridge properly myself? I have never installed a cartridge before. I realize it would be easiest to just pay somebody to this for me, but this is something I would like to learn. Should my first step be to buy Fremer's DVD? Thanks for your help.
