What tubes do I have here?

[80's_Thrash_Metal]

I bought these quite a long time ago off somebody somewhere, could have been eBay.

I don't know what they are? 2 of them are crooked in their bases.
I know one of you tube gurus can identify them.

The box just reads el34 and NL40

Looks like NOS TungSol EL34 to me. But since you don't know, you'd need to find some additional markings on the tube, even looking for the faded remnant of some branding would help narrow down. I think the 40NL is just saying they are matched with some tester.

I dont think it's Chinese because I dont see the spot welds they most often use to affix the side rods (what holds the Getter, Electrodes, Grid and lower leads) to the the top and bottom insulating plate/spacer

They're Chinese are so are your other Marshall tubes.
