    Abstract: The disclosure is of a cold cathode, gas-filled indicator tube which includes an anode electrode and a stack of cathode electrodes in the form of characters which face the sidewall of the envelope as a viewing window. The envelope includes a base or stem which is generally flat and carries tube pins which are connected directly to the lower ends of the cathode electrodes. The upper ends of the cathodes carry tabs which slip into, and are held in, a tray which has an open side and a slotted bottom wall. The tray may be made up of two identical parts, each having an open sidewall for receiving cathode tabs.
