It looks like the original Matamp layout has additional chassis shielding in this area.  I'm using Cliff jacks and my chassis is powder coated, should I be using shielded wire here?

Would it be better for me to solder the grid stoppers directly to the tube socket, and run a shielded cable to the input?  Ground at the socket?
