I am confused. First we were on the 3-500Z of these guys amp, now on the
4-1000A. Anyhow, Rich adding any kind of thin wire to a grid to ground
path vs. having the grid directly grounded with a very short piece of
braid does add more inductance. However, sometimes adding the inductance
is necessary for moving the resonance point.
