It was a nice matched quad, but one of the tubes in now in tube heaven. The getter is now a halo

Another related tube - KT66. I bought several NOS quads all matched thinking they would last 5,000 hours. As it turns out, they last much longer.
I don’t know how many hours I have on my GEC KT66. I got those clear glass shown in my amp over 20 years ago and they were used, have used them for thousands of hours and they still test the same. Just a touch below brand new. Try that with a Chinese or Russian tube.
And I have never had one red plate, get gassy or have unstable bias. Awesome tubes!
These are the earlier version before Mullard's big black plate twin ring getter
This could be the rarest GZ34 you ever seen, production in June 1957 before the termination of the metal base GZ34 series at the Eindhoven factory
As I understand it, the VALVO tubes are supposed to be exceptional…………is that correct?
I hope so. Never got a chance to try them since I already liked the KT-66 in those applications.
I think I may have collected too many tubes.
Collected too many tubes? Don’t be silly! You can never have too many tubes!…………interestingly I just purchased a quad of Psvane Horizon EL34 ( Chinese tubes I felt were problems in the making ) but I heard so much good about the Psvane that I had to order them. Would have loved to have a shootout with the VALVO and the Horizon - I can only dream I suppose.I hope so. Never got a chance to try them since I already liked the KT-66 in those applications.

6n3cE (often called 6P3S-E in North America), a very nice sounding Russian 6L6GC variant. On the left is two quads I purchased from Jim Mcshane around 15 or so years ago when they were still available, on the right a full box directly from Russia with 36 tubes of 1970s and 1980s vintages I picked up from a guitar player in town just afterwards.
Very tough long lasting military tubes (I’ve only ever used the first quad from Jim and after a thousand or so hours they still test new). They were once very common but the word got out and they have now become difficult to find.
