Has anyone found that the Pearl PCF or Herbie's Tube coolers/dampers have helped extend the life the tubes they have used them with? I'm just curious.
Also regarding Gundam91's post about putting a ground wire on each of the Pearl PCF tube coolers. My tube amp has a ground lug in the rear. Would I connect the wire from the tube cooler to the ground lug? I'm thinking I would need to connect the wires from each of the coolers to some other metal chassis.
