Опис
Продам красивый ламповый пред китайского производства, состояние нового, наработка ламп от силы месяц.
Инфа от производителя:
Input impedance: 100K
Output impedance 2K
Output voltage: 2V-20V
Frequency response: 10HZ-100KHZ
Distortion 0.2%
Signal to noise ratio: 96DB
HIFI preamplifier assembled and debugged with fever concept
[Instructions for material use]
1, using two-stage direct-coupled amplifier circuit, strong bile flavor, deep extension at both ends, large dynamic range!
2. The high-voltage filter capacitor uses PHILIPS 150UF 450V × 2 (other originals are brand new), Aihua AISHI 15UF × 2 auxiliary filter; the output coupling uses Hong Kong TE MKP copper-pin antique film capacitor 2.0UF + 0.1UF in parallel, the sound quality exceeds WIMA, ERO, etc Brand.
The input coupling capacitor uses Vishay MKP 0.33UF.
3. The signal path uses pure copper wire, and the RCA terminals are gold-plated. . Laying the foundation for high-quality transmission of audio signals. The power socket is made of nickel-plated copper.
4. The resistors are all made of domestic precision metal film resistors with high signal-to-noise ratio and good stability.
5, using Japan ALPS 16 volume potentiometer, no noise from other miscellaneous potentiometers, long life and durability.
6. Red walnut log luxury case, 2CM thick solid wood non-veneer, rose gold mirror stainless steel top plate, overall dimensions: width 160 height 160 (including tube height) depth 300 (MM). The net weight of the whole machine is 2.8KG.
7. The PCB is designed for the chassis and strictly follows a little grounding principle. The output of the transformer also corresponds to the position of the PCB terminals. The layout of the wiring inside the box is reasonable and well-organized. The power and signal lines do not cross and overlap, which effectively reduces the chance of mutual interference! It really takes a lot of effort to design this product!
8, 6Z5P tube bile rectification, multi-stage filtering and IRF840 MOS tube voltage stabilization, to provide a stable and pure power for the front stage. More suitable for use in areas with large power fluctuations. With 10H 100MA choke coil (No. 573012), the filtering effect is better, which is reflected in the music playing a little more flexibly.
9, high-quality all-copper wire 50W E cattle (number 664410), the tube filament uses 3.15V-0-3.15V AC power supply, so that the sound quality is more flavorful, while the bottom noise of the whole machine is only weak 3MV, this is the designer A profound manifestation of skill. The imported high-quality H50 annealed silicon steel sheet has a lower temperature rise than ordinary silver sheets.
10. Standard electronic tube: Sugon 6N8P * 2 (replace model 6SN7, 6H8C, CV181); Sugon 6Z5P * 1 (replace model 6X5)
Торга нет, отдаю по себестоимости.
