W: datasheet to NEC LD4389A TWT

Hi, I'm looking datasheet to older traveling wave tube, manufactured by
NEC, model is LD4389A. I have full amplifier with power
supply+schematics, but no data for tube. Amplifier gives over 10W in
10368MHz, but I don't know what is safe level to helix current and how
much tube can be punished
