Hi,
Ive just bough a new tube to replace the tube which came with my amp which had a fault.
(http://i76.photobucket.com/albums/j23/pnooud/74F43C88-9D47-4BAA-95C0-47FB613893E4_zpsstx7s9sa.jpg)I just wanted a cheap tube to check if mine was faulty, so ordered one cheap off eBay that was in the uk, so would be delivered quick, The I ordered a brimar 12au7, but I got a tube that has the brand ZaeuX (or maybe ZaeriX) on it, the guy also gave me a second tube as a free gift which is just labeled 12AU7A, with no other branding.
With the Zaeux tube, there is a little more treble and you notice listening to a track with a busy drum section, the drums seem to have a bit more texture.
The non branded tube was a bit smoother sounding and sounded a bit cleaner, but its not got the same energy.
I prefer the sound of the Zaeux personally.
It would be good to know if it sounds better or worse than the original tube that came with the crack; I seem to remember the original sounding better, but that could have been the glass of single malt I had
Where should I go from here do you think, I am wondering will I get much more detailed sound etc spending a bit more?
