Vacuum Tube Mullard EL34 Replace 6CA7 Kt77 KT90 5881 6P3P Electron Tube Factory Test And Match Be used for Amplifier Audio
Note: Ship after inspection(After receiving the tube, please do not think it is a fake or shoddy product).
Regarding matching:
We have the conditions and advantages to match multiple tubes (four, eight, ten) according to customer needs. The parameters are the same)
The British Mullard EL34 is characterized by a thick voice and warmth. Compared with other brands, it is more honest and charming. This is the reason why it is regarded as a classic by the old Guan fans. The old British Mullard is so scarce that it has become the coveted celebrity tube of global enthusiasts, so the US NEW SENSOR Group¡¯s celebrity tube regeneration plan chose the Mullard EL34 for the first time.
In fact, the NEW SENSOR Group wanted to use a design similar to EH EL34 to achieve the old Mullard tube products, but because of different machines and different production lines, the sound performance is compared with the real Mullard, lacking some thickness and warmth, and the trend is more modern. , The tone is far from the old Mullard.
After obtaining the machines with the same trademark as the original production line, NEW SENSOR Group also recruited British engineers at the time to serve as consultants to train a new generation of engineers and operators. They moved to St. Petersburg, Russia, and made use of local high-quality engineering manpower to join the world. Supported by the old OTK technology, the Mullard EL34 was successfully reproduced.
The new re-engraved version uses the same vacuum equipment and metal materials as the original, and even the material and thickness of the glass bottle body, and even the pin solder ratio, are implemented in accordance with the original tube`s technical manual. With the new manufacturing process, the quality and sound quality are more stable due to the addition of automation machines in the new era. The electrical characteristics, including the endurance of high voltage and the life span, are much better than the old pipe, and the noise suppression and structural strength are also improved.
Sound is the ultimate goal. Compared with the old tube, the sound similarity should be said to be relatively close. The sound quality characteristics and the sweetness of the intermediate frequency are very charming and very similar. The re-engraved version is still a little bit behind the old tube in terms of the thickness and warmth of the mid-range, but the re-enacted version has certain advantages in terms of delicacy and high-frequency air. Overall, the re-engraved version is quite successful!
