Supposedly the change is tied to the SN#. You need to contact Tekton with the SN# and they will tell you.
Here’s a video summary on the resistor change

If you are using anything with equalizer capabilities , such as JRiver, you can lower the 600hz and the 1khz by about 1.5 db to 2 db(depending on how forward your amp pre-amp and cable combination sounds ) for very close to the same results,without having to install any resistor.
It seems to lower ,IMO,mostly the vocals area. This lowering of these frequencies allows the bass to become more prominent. I think this is a desirable effect for most people.
I actually have mine at -1.5 db for each of those frequencies.
Seems to work well for me .
