The working voltage of the gallbladder is over 300 volts, which is ten times and twenty times that of a regular transistor power amplifier. It performs very well in the details of music, and with rich even harmonics, it gives a soft and mellow listening experience without losing its brilliance. Old songs are always enjoyable to listen to, and can be performed well in conjunction with our specially customized full frequency speakers, vocal strings, and other business venues that require background music. This EL34 gallbladder machine is completely based on the traditional circuit gallbladder rectification CLC inductance filtering, and the fixed components are meticulously wired and welded by hand. Each machine can be customized for you, and the exquisite craftsmanship and beautiful sound are excellent products for your collection and gift to friends.

The basic configuration is a simplified version with four black pipes and a small volume. The standard configuration EL34 finished gallbladder machine has a net weight of 8.2 kilograms. The dzdn29 design has a simple and sound like circuit, and the 6H8C pushes the EL34. It adopts dual 290V gallbladder rectification and CLC inductance filtering. The default power of the entire machine is about 10W with a super linear connection, and 8W with a transistor connection. It can be used to push bookshelf boxes or floor boxes with a sensitivity of around 100W and a sensitivity of 88DB or above. Listening to vocal strings is enough, and it is not recommended for those who like DJs or turn up the volume to make noise, You can purchase our push-pull or ordinary amplifier from our store. The power consumption of the entire machine is 105W, the power transformer is 160W, and the remaining power is 55W. After starting up for 2 hours, the temperature in the northern summer is slightly higher than that in the winter, and it is only warm, which can ensure continuous startup for 24 hours. The output transformer adopts 0.35 audio specific Z11 silicon steel sheet imported from Japan, with a tongue width of 22 and a stack thickness of 45 or 50. The large caliber landing box with high sensitivity in actual listening experience has powerful and powerful bass, rich and soft mid frequency vocals, and crisp and clear high-frequency vocals. A song by Cai Qin's Ferry is intoxicating, even when used to listen to popular dance music, it can be shocking. The strength of the bounce and clear interpretation make people listen tirelessly.

The background noise of this device is mostly between 0.5 millivolts and 1 millivolts. When the volume potentiometer is turned down, only the ear is pressed against the speaker to hear weak communication sound. The noise caused by turning up the volume is closely related to the signal cable used and the quality of the CD, and is not the background noise of this device. Buyers should pay attention to this.

The input voltage can be made into 220V, 240V, or 110V. You can contact customer service as needed and send 220V voltage by default.
