Clever people,


After a couple of weeks' waiting time, my first four 6CS7 (NOS) tubes (for a Leben CS-600 amplifier) arrived yesterday by mail from the US.

I think they're beautiful. My plan is to get three to four 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 - including how old they are.

Some pictures below.

Thanks in advance,

Kasper
