Description

NATIONAL POWER TUBE NL-710/6011 is a quick heating thyratron designed especially for ignitor firing and regulated rectifier applications. It is gas and mercury filled for quick starting and constancy of character- istics within wide temperature limits. The NL-710/6011 with the lug type base is designated as the NL-710L.
