To install the R136, proceed as follows:
1. Holding the microphone upright in a vertical or near vertical position, remove the screen assembly. Grasp the
cartridge case firmly and remove cartridge assembly from the microphone (see Figure 1).

For microphones with three leads connected to the old cartridge, before soldering leads to the R136, place the
supplied solder terminal and hex nut over the center screw at the rear of the R136. Position the terminal away
from the other solder terminals, and carefully tighten the hex nut (see Figure 2). Solder the microphone’s black
lead to this terminal.
4. Insert new cartridge in microphone case. Make certain that projection on bottom of shock-mount seats firmly in
notches in case, and that shock-mount is centered in case and does not catch on the side of the case.
