A stack of plates is surrounded by a sleeve manifold which is shaped to provide manifold chambers, and including surfaces for seals to isolate the manifold chambers from each other. A source extending region is provided adjacent to the transistor region or in the transistor region, and a source interconnect layer is designed to protrude from the upper end of a trench. Additionally, the method for amplifier distortion measurement includes equalizing the first amplitude response of the output signal to match the second amplitude response of the reference input signal based on the set of AM-AM distortion values and creating a difference signal based on a comparison of the equalized output signal to the reference input signal. The clips are oriented perpendicular to the plane of the face of the rods or welded fabric such that the clips are attached by applying a force perpendicular to the plane of the rods. Each cutting blade has a retracted position minimum gauge cutting portion and an extended position maximum gauge cutting portion, with the blades in the extended position the gauge cutting portions extending axially and being located in a transverse plane on or forward of the blade pivot axis.
