Vacuum Tube - 6AU4GTA, Diode, Damper
New-Old-Stock (NOS) tube.
The 6AU4GTA is a single heater-cathode type diode intended for service as the damping diode in the horizontal-deflection circuit of television receivers. Its high output current capabilities make the tube particularly well suited for operation in conjunction with the 6CD6GA in autotransformer deflection systems. Except for increased maximum d-c output current and peak plate current ratings, the 6AU4GTA is identical to the 6AU4GT.
