Reply to Fixing/Replacing Touch Sensor Level

Does anyone know of a way to fix or replace a touch sensor level adjustment found on the back of the VCI-100 my problem is this when I bought my VCI-100 one of the touch sensor levels broke the first time I tried adjusting the stupid thing unfortunately for me that's the one damn part on the VCI-100 that wasn't built like a tank.

As a result though I haven't gotten much use out of the device because some how it's attached with the cross fade curve on the back as well apparently in some way or another. If anyone knows anything helpful let me know would appreciate it. I figured since this is the mod section maybe someones knowledgeable enough to have a easy enough solution perhaps.
