I've searched the forum and google and come up empty handed on this. What I'm trying to find the dimensions of the rubber piston inside the Lunt pressure tuners? I'm trying to figure out how doable it is to make a manual adjustment of pressure (using the automotive "pistol grip" unit mentioned elsewhere) with readily available parts. Any thoughts, pointers, experience with this mod would be appreciated. I don't need computer control, but I suspect my hands/knuckles over time will thank me.
