Luge 6V6, 6P6P, 6P3P, 6P14, 6P1 and other electronic tube push-pull 20W output transformers: model LG EI66-340.   Imported EI66 iron core, silicon steel sheet with a thickness of 0.35mm, tongue width 22mm, stacking thickness 36mm, iron core piece by piece, high-quality nylon wire wrap skeleton, Taiwan assets Pacific high-quality enameled wire winding, vertical installation, with left and right cow covers . The input impedance is 10K, and the output is 4/8 ohm. There is a super linear connector, and a 5-layer 10-segment winding process is adopted to minimize the leakage inductance and distributed capacitance.   Inductance is greater than 25H-40H (1V100HZ measurement), leakage inductance is less than 15mH (1V100HZ measurement), distributed capacitance 560P (15KHZ measurement), primary DC copper resistance 330 ohms, secondary copper resistance 0.3 ohms.   The shielding shell is made of high quality steel plate die with a thickness of 0.8mm, weighing 1.09Kg/piece   ************************************************** ************   A brief introduction to the 10K push-pull output transformer.   10K push-pull impedance is the most common impedance for tube power amplifiers, because the first low-power tubes are almost 6P1, 6P14, 6P15, 6P6P, etc. These low-power tubes are good and cheap, and most people play it. If you want to increase the power Only push-pull lines are used, almost all of which are 10K impedance.   The output transformer is the soul of the tube machine, which directly affects the sound effect. After more than half a lifetime, there are always dozens of classic 10K push-pull circuits, and it is even more icing on the heels of high-quality output.   To make this transformer, in addition to the use of good materials and strict design, the rest is winding and debugging technology. The common layered and segmented winding method can basically meet the normal listening requirements.   In order to pursue better and perfection, after continuous exploration and research, searching for information, comparing and dismantling famous cows, proofing, testing, and listening to the sound, we finally found a different way, adopting the king-shaped skeleton structure and winding method that many top-level robotic cows also use. The upper and lower windings of the push-pull are divided into two independent coils. The winding and process are completely the same. The two coils are combined in series and parallel to form a complete, symmetrical and balanced push-pull output transformer.   Both wire packs adopt 4-clamp 3 technology, and each winding adopts forward winding and reverse winding to reduce distributed capacitance and potential difference and widen the bandwidth. A total of 14 windings and 28 thread ends, this structure is also a common method used by many foreign HI-FI famous machines {some are more complex, such as the output of a wheat map}, and it is also a method often used by senior amplifiers. Achieve extraordinary results.   Combination wiring is a time-consuming and careful part of the entire procedure. Fortunately, the master does professional and skilled work every day. Practice makes perfect. You can also make a dozen wire packages in a day.   This transformer has been sold for many years, and many colleagues and fans often come to learn from it, and the effect has been verified and affirmed. The original model of this cow is SHDX-66-340, which is now reproduced.   Many of the machine push-pull transformers in this department also use this process structure. The sound effect is better than other products in the same price range. Welcome to compare PK.   As a designer of output transformers, you must have a long-term love and pursuit of music, a certain sense of music theory, a solid electronic foundation, proficient and relevant test equipment, high-end audio equipment, and years of experience in installation and debugging. , I often listen to famous machines compared with famous cows, only then will we know the gaps and have the ability to improve and improve.   If a seller who only winds transformers and sells cattle but does not install them for use, it would be foolish to say how good their transformers are.
