Shame it doesn't work, 34 Deluxe is my favourite colour (produces blue end banding) but they are almost non existent here now.

3L i would take a guess November 1993?

It's Nov. 1973! The /34 was dicontinued in the early 80's in favour of the new efficient 94 (940) white De Luxe.

You could short the open end and move the starter out of circuit and it should run.

@Monkeyface. Cool i was just thinking if it was 73 it might of had the crimped ends. I was thinking about 73!

I will try to start it up

@ prismatic; good luck

@kev; i believe that the change between the crimped and the later endcaps was around '72-'74.
all my new TL-M 40W/34RS from May 73 are having the crimped ones...

Cool. I really could start it up I've made a video and posting it on my youtube channel (the magentic ballast made some unhappy sounds )

@Monkey face, Yes i have a 71 U tube with crimped ends, A couple 73 4' with crimped ends but a 75 2' with later ends!

This is an odd tube. It's indeed from 1973 (November) but it's not a regular Dutch /34 tube: font type is slightly different and the symbol indicates production location Hamilton, UK. The "imp" may stand for imported. My guess is that this tube was not for the UK market but for export to other West-European countries.
I also noticed that the UK hardly ever got "De Luxe" colors from Philips at that time. All I have seen so far are with mediocre CRI like color /29, /33, 35...

Definitely November 1973.
