Barang ready kak, jika mau request silahkan tulis di deskripsi kak, jika tidak kami kirim random, beberapa barang dikirim dari gudang berbeda kak jika barang habis
Note: During the actual assembly process, due to the requirements of sound calibration, some components may be different from those in the pictures.
Features:
1. Layout, each area is strictly isolated, so that the signal-to-noise ratio is as high as -109.6dB, and the background is extremely clean.
2. The non-broken belt ring cattle iron core transformer is potted in the iron cover, so that the vibration is reduced to a minimum.
3. Two sets of filaments are powered, and both have done a slow start. It takes 8 seconds to turn on from 0V to 12.6V, and the filaments will slowly light up when turned on.
4. All low-voltage heating elements are mounted on the 10MM thick isolation, and the heat of the whole machine is well controlled.
5. The high voltage uses a bile rectifier.
6. All-aluminum chassis, the front panel is 10MM thick, the two side panels and the back panel are both 4MM thick aluminum panels, and processed by CNC, the craftsmanship is extremely outstanding.
7. Special PCB manufacturing process.
8. All copper RCA socket, 4 groups of signal input and 1 group of output.
9. Extensive use of audio-specific capacitors.
10. Applicable to global voltage standards.
