In Reply to: Amperex Bugle Boy 6DJ8 overrated? posted by jlingo on February 2, 2007 at 06:42:09:
Tubes could sound very different even though they appear the same. 6DJ8 gets much higher selecting rejection than 6922 which was born to be a premium version tube. That's also for the reason why generally people hear better sound from 7308.
I really hate to say it, but I have reservations about the
white print 60's vintage Amperex's even being the same tube.
I know they were purportedly just better matched section to section
and quieter than 6922 or 6DJ8's.
However, the rest of the family has a strong sonic resemblance
be it 6922's, Bugle Boys, Pinched Waists, D-getters or small/large
ring getters, later orange print or world logo's, etc.
The 7308's sound far different. The soundstage is
way deeper,with a farther less immediate in-your-face presentation.
It has not been subtle in my various testing.
I know it's heretical to suggest, but the USA 7308's do sound more different IMHO than any of the other Amperex's, be they Holland or US production. Whether or not Hollands sound better than USA production, seems to also depend on the specific system and component they're used in.
I would agree that the early Amperex/Philips tubes be it 6DJ8 or 6922 with small, large round getter, or D-getter sound quite similiar(never tried the pinched waste). These all have the same basic plate structure, closed. I find the USA made 7308 of this vintage to be similiar in sound to these early Holland produced 6DJ8/6922.
Where I hear a difference is with the later Holland production using the open plate structure. I have white, orange and world globe print of 6DJ8/6922(no 7308) production circa late 60's early 70's. I don't care for these tubes compared to early production. They are brighter, thinner and lacking dimensionality compared to the earlier production.
Thank you Edison, I felt much better now. Does anybody have any recommendation where i should get my Bugle Boy 6DJ8? Tubeworld.com? There are so many varieties and It's very hard to decide which one to get without first listening to them. Even then, there are so many different kind of 7308 Amperexes in tubeworld.com and it's very hard for me to decide which one to get first. I don't even know whether the sound signature would be similar or not between 7308 Amperexes type.
