I think rectifiers can have a very long life depending on obvious factors.
To be honest I've only listened to it for maybe 10 hours. I put it into my amp, Woo Audio WA6-SE, to test it out and to give it a listen. I'd say that the review of it on page one does a great job of describing the character. My primary rectifier is a GEC U52, which I absolutely love. Compared to the U52 it does have a little bit more warmth. It also has a more visceral bottom end. It's absolutely a classic tube and I'm happy to own one. I'll keep it as a backup for when my U52 goes out one day. At that point I'll use it as my primary. But yes, a great, great tube in my book.
