Hex Screw Wrench Size for RK100PK Preamp

FAQ #3714 Updated October 26, 2017


I need to get inside of the RK100PK preamp to change the gain. This requires the removal of a small hex head set screw. I do not have the hex screw wrench that was packed with the MX mic. What is the size of the hex screw wrench?


The wrench size is 0.050 inch or 1.27mm.
