1970 0009 (Misprint)

15.5mm numeric tube manufactured by National Electronics

The 1970 0009 is a clear glass numeric tube manurfactured by National Electronics. Sadly i don't have any info about this tube, but this tube is very special. The National Electronics is misprinted in "National Elecsronics". Since the print looks very genuine and similar to other tubes of National Electronics, this probably a real mis-production.
