My Tube Collection, Welcome to share yours

How did you get one mark! This one is indeed hard to find. Did you try in your lampi?
Oh it was a gift from a kind customer Ian and you can read about it in post # 651 below. We can compare it to your engraved WE274b when you visit :)

Are any of our resident tube gurus able to identify the manufacturer of this 6n7gt? There aren’t any markings on the tube, beyond those of the relabeller / distributor and I believe they are @1967 western european production.

You guys are amazing - you make me realise what little knowledge I have of tubes.... stuck in my little world of 12AT7, 12AX7 and EL34s. There is actually a huge tube world out there! :) Very interesting to see, and I bet hear too!

Very rare 6SN7GT labeled Rogers. The plates (large three hole Tplates like ”Badboys” plates) look like Sylvania, but those ”umbrella “ spokes down from the top mica are reminiscent of the Raytheon 6SN7WGT. I have never seen a thin rectangular getter like that before. Found at the bottom of my stash, now my current favourite as driver tubes for my amp. You just never know when it comes to tube rolling…….
