After extensive testing of lamps in Brand Manufacturer preamp, I decided following an article seen on the mesa site describing how they sort of lamp is draconian by myself to see if the quality was at the appointment.

Usually I am rather anti retagués tubes (yes, mesa is no tube, they supposedly sort and retaguent with their logo), but I thought that I had to test by myself not to argue the supposed fact.

I have already been tested in the past a lot of 12AX7/ECC83 to be exhaustive:

Tung-ground Reissue 12AX7 gold pin and version.
Sovtek 12AX7-WA, WB, WC and LPS
-JJ/Tesla ECC83 and ECC803s and the gold pin versions.
-Mullard reissue.
Electro-Harmonix 12AX7
Sino 12AX7-A,...…

SV-12AX7 Svetlana-.
Phillips-JAN-12AX7 (NOS)

This time I bought four 12AX7-A mesa home to see if they sort it possible to obtain excellent sound quality lamps.
And to my great disappointment, not at all.

4 new lamps on the four caused the blast on the first day,
2 / 4 caused a small crack guitar same volume 0. and the worst, 3 / 4 were the first microphone to use! ! !

So sorting hyper selection realized by mesa boogie, it's great shakes, grabs the sucker who wants to believe it.

Although these lamps have a color sound drinking (a closer look, they are JJ / Tesla ECC83 retagués) it is of very poor quality, no sorting worthy of the name has been made.

I put three to zero does not stick directly, but it is the equivalent of buying lamps damn!

I have used for a month on a HK tube 20.

after one month of a lamp has a default surment lach ...

the level I found them disappointing compared to the groove tube 12AX7 sound is less warm, with highs drier and less bass prsentent ...

it is mainly the lack of heat from my ... So I remi my groove tube.

So for me not photo, enter groove and mesa boogie tube (12AX7 level), the groove tube are much better
