***The vocal weapon, the model of EL34! It is the most classic EL34 power amplifier, suitable for buyers who listen to music. The actual maximum power of the push-pull circuit is 40W. It has very good thrust and control power, which is equivalent to the thrust of 200W of Class A and B stone machines. It can push most households well. Speakers and bookshelf speakers, one-step choice!

     As the most classic tube amplifier circuit, there are endless imitations and improvements by countless enthusiasts both in the past and now. We have also compared and tested the products currently on the market. Finally confirmed the current circuit layout.

In 1904, the birth of electronic tube devices (also known as vacuum tube devices) brought a revolution in the field of traditional audio. Today, the electronic tube still has a special status and unique application, and is affecting the PC multimedia audio field, because many of its characteristics are not available in transistors.

    As a“voltage”amplifier, the working principle of the amplifier is different from that of the current amplifier of the transistor. The signal distortion characteristics of the electron tube are far greater than that of the transistor. The even harmonic distortion of the signal in the electron tube amplifier circuit is large, and the odd harmonic distortion is small. The transistor is just the opposite. The electronic tube amplifier circuit has a relatively high overload capacity. When the instantaneous peak value of the input signal is overloaded, the electronic tube will not have obvious clipping, but only round the peak value. This smooth effect can maintain the relative integrity of the signal. In contrast, the transistor will directly clip.

The working voltage of the tube amplifier is ten times or twenty times that of an ordinary transistor power amplifier. It performs very well on the details of the music. With the rich even harmonics, it gives people a soft and mellow sound without losing its beauty. An old song Let people never tire of listening, fine handwork and beautiful sounds are your collection.

=======================Why is the price of the push-pull EL34 power amplifier so high? Some machines on the market are only in the early 2000s. Take a closer look. The most critical cost is the output cow, power supply cow and the chassis. Only genuine parts can make products with sound compliance! The cost of our chassis shell is more than 300 yuan more than any big brand, not to mention the gap between circuit components and RCA terminals.）===============================

The price of EL34 in our store is estimated to be higher than other stores, the main reason is the big difference in materials. For an electronic tube amplifier within a thousand yuan, the shell only uses a metal box and an aluminum panel, and most of it uses only thin stainless steel in the box. The box used in this machine is a 7KG all-aluminum process shell. The atmosphere is stable, but the shell cost is more than Similar products are more than 300 yuan, in addition to appearance, it is very helpful to suppress the resonance of the whole machine.

In addition, the output transformer is used in Japan''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s good Z11 transformer, so that the high frequency is delicate and extended, and the cost is nearly 100 yuan more. Take a closer look at the details, the RCA output also uses the American CMC-816 terminal.

It will be more than a loss to upgrade each piece.

PSVANE（Chinese name: Voice of Noble）In fact, it is not a particularly unfamiliar brand. As early as the end of 2009, PSVANE Noble Voice had independently developed and relied on Hunan Changsha Shuguang to launch the PSVANE T series of tubes. The models cover HIFI commonly used models. Both sound performance and craftsmanship are well received. sure. And in 2011, PSVANE''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s noble voice brand made a big move that shocked the world HIFI industry. Their core development team separated from the dawn and convened industry elites to form Changsha Hengyang Electronics Co., Ltd. in Hunan. The core business is It produces and sells various types of electronic tubes and electronic tube audio amplifier products under its own brand PSVANE. Not only that, they also acquired a well-known electronic tube factory in southern my country in one fell swoop. The overall scale is currently among the top three in the world. As for the tube amplifier, its core technology is nothing more than electron tubes and transformers. PSVANE Voice of the Noble is currently the only brand in the world that has independent design and production capabilities for tubes, transformers, and coupling capacitors.
