Review
Note: this is a diy kit. all the Components will need youself to solder them!!!
There are some SMD Components and SMD opamp on the PCB back side. Please make sure you are skilled in welding these SMD Components.
works voltage: AC110V or AC220V
PCB size: 330MM*185MM
support 2 way RCA input / 2 way Balanced input
1 wau RCA output / 1 way Balanced output
Advanced double-sided thickened gold-plated PCB (substrate 2MM, copper foil thickness 75U, not 35U comparable).
Transformer, rectifier filter regulator, audio switching, volume control, all built at one board, tree-like ground alignment, higher signal to noise ratio!
Relay volume control signal channel all use 32pcs 0.1% high precision military 718 plant resistance (left and right channel balance to 0.1%)
By adjusting the potentiometer (the potentiometer does not pass the music signal, only play the role of control relay) control 16 (Japan imported TAKAMISAWA relay) switching resistance to complete the 256 step adjustment, no explosive sound, pure resistance circuit than the traditional carbon film Potentiometer fidelity is high
25W power transformer,
Filter capacitor with four 35V4200UF ELNA blue robe electrolysis,
Regulator with two new ON LM317,
Subsequent electrolysis using Panasonic gold FC series.
Balanced amplification line with four new authentic LM4562 op amp.
