Dating of 4 6CS7 (NOS) tubes from Sylvania
type: item
description: Clever people, After a couple of weeks' waiting time, my first four 6CS7 (NOS) tubes (for my Laben CS600 amplifier) arrived yesterday by mail from the US. I think they're beautiful. My plan is to get 3 to 4 good quads - if not exceptional - so that I have enough for a lifetime. Estimated lifetime is often said to be in the 10,000 hours range, perhaps. I'm looking for a bit of history of these - e.g. how old they are. Here are som pictures: Some additional images here: https://bergholt.net/6cs7-sylvania Huge thanks in advance, Kasper
