In Reply to: Amperex Bugle Boy 6DJ8 overrated? posted by jlingo on February 2, 2007 at 06:42:09:
...it all depends on system synergy and of course one's personal tastes.In my gear, ARC, the Amperex Bugle Boy 6DJ8 is by a fair margin much better than any other tube I have tried. I have tried all the ones you mention and many, many more. Probably around 50 in this family.
If anything the Bugle Boy is underrated. All the other European 6922, 7308 variants are oh so sexy, and certainly command huge, inflated prices.
Just wish my SP-10 did not eat the BB. The Mullard 6922 is the closest tube I have found to the BB in the SP-10 and they last.

Tektronix generally screened their tubes well. If they are new they probably sound good indeed. Only cavaet would be noise. For their intended application noise was not an issue. For audio it can be.While I prefer the Amperex BB versus any of the other variants in this family, the BB can be noisy. Screening for noise is mandatory with this tube.
At 1mv/cm using a x10 attenuating probe your gonna need a lot of gain and pretty low noise. ;-)

I have seen Amperex BB tubes (without the Tektronics sticker) pulled from Tektronics gear in the past.With 6DJ8 type tubes, if they are not “NOS NIB No Shit” they may well sound like shit.
There are a TON of “pulls” out there being sold as NOS and in some of these industrial applications they just ran the shit out of them.
I’ve got about a dozen marked as Hewlett Packard made in USA packed in cardboard tube and with “B” etched codes indicating they were made by Mullard in the UK.
Hope to build something someday to take advantage of them.

All of the 6dj8s that I have pulled out of old scopes are used up.
These are new, never out of the box and test new on my 533a. I bought them from a antique store with a batch of NOS NIB JAN tubes for .50 each. I got a pair of NIB NOS RCA 5691s in that same batch. And a pair of GE five star 5751s.Tre'
