New-Old-Stock (NOS) tube.

The 26LX6 is a compactron beam-power pentode primarily designed for use as the horizontal-deflection amplifier in color television receivers. It is characterized by having a very low knee with a very high peak current of over an ampere. This results in a basic capability to scan 90-degree large screen color picture tubes at 25KV from 280-volt power supplies. Its low knee minimizes "snivets" without the necessity of supplying special voltages ot the beam plates.
