Alors à la base, on parle de la 12AX7A, maintenant on trouve des 12AX7B.
Je n'ai pas de "B" donc je vais pas en parler.

Shuguang 12AX7A Audio Tube ThumbnailShuguang 12AX7A (Discontinued) - When the tube stockpiles dried up in the 80’s, and before modern tube production ramped up, there was little available on the market except the Shuguang 12AX7. These have been in production for decades, and while the factory has changed locations over time the tubes have remained unchanged. Many amp companies have made this tube a stock component, two of the biggest companies were Peavey and Mesa Engineering. The design is interesting and unique. Two small dual triodes separated by an isolation plate and held in place with 3 mica spacers. These little tubes are notable for their high gain. They tend to be a bit gritty and bright with a little more background noise than most. It’s the price for high gain. Most frequently used by hard rock and metal lovers for all of the reasons listed above.
Shuguang 12AX7B - Although this tube is listed as a variant of the 12AX7A there is really very little difference to discuss. For all intent and purpose this is a 12AX7A that has high gain and low noise. Shuguang discontinued the 12AX7-A vacuum tubes in recent years. One thing that I will say about both the A and B, is that they really sound good for rock and roll. If you are having noise and microphonics issues with the A variant but want to keep the gritty attitude, then you should try the 12AX7B before you move on.
Et de toutes façon je les prendrai chez TAD à titre perso, parce que si le tube lâche, tu peux négocier avec eux.
