Electronics modifications—no!
The problem with detailing any changes to the SM81 electronics is that they have changed considerably over the quarter of a century that the microphone has been made. The Bevan paper cited below has a schematic of the original design, but if you open a current SM81 you will find the schematic is very different.

Thanks .Not looking to mod it, I am having an issue that I think maybe a filter cap feeding back in the mic.
