In a cathode ray display tube including a screen carried on a flat faceplate of an envelope and a channel plate electron multiplier arranged parallel to, and spaced from, the screen having an input side across which an electron beam is scanned and an output side from which a current multiplied beam is directed onto the screen, the multiplier is supported away from the screen by a spacing frame engaging with the periphery of its output side and is clamped against the frame by a pressure member having a plurality of resilient fingers spaced at intervals around the edges of the multiplier and engaging with the input side thereof. In this way, minor local surface profile variations of the multiplier are accomodated. The fingers serve also as contacts for the input side electrode of the multiplier.
