I have never tried it on a g07, but oddly enough I do have one on my workbench, And as grants says apparently it is correlated to the yoke resistance, I am hopeful it will work, since I do love those chassis but normally use them on 20 in tvs, Reality suggests those TVs are more 19" anyway, and with adjustments to deflection never seen a problem with any abuse to the tube... They (the chassis) do seem to have limited adjustments however, and seem quite not quite right without some fiddling around, But Do not move the yoke, It will not help, and will only mess with the convergence.
