LG233 6J8 two-channel preamplifier board: 6J8 tube has a strong bile taste and excellent vocal performance, which can create a simple and beautiful sound line.
6J8 can be exchanged and upgraded with imported pipes such as EF86.
Exquisite FR4 double-sided glass fiber board, high-quality PCB board, size 111mm×70mm. High-voltage DC 183V power supply, filament DC 6.3V power supply, one-point grounding, the line is quiet.
The two-sided character of the resistance-capacitance element can be assembled on both sides, which is suitable for the installation of exposed pipes.
Liangyin's American EC 0.1 u 850V tin film capacitive coupling (tin film capacitors have special electrical properties, can produce beautiful sound, different from other capacitors) or German WIMA Weimar coupling. Imported domestic metal oxide film resistors, silver-plated ceramic tube sockets, high-quality binding posts, two small nine-legged 6J8 domestic ones, can work when connected to the power supply. 6J8 and EF86 are interchangeable.
Because the color of the different boards in the production batch will be different, do not choose!
Note: The EC components on the board are used disassembly parts. The finished board has been powered on and tested, and the power supply cannot be connected wrongly when used. Due to different preparation or assembly batches, the brands, specifications and parameters of individual components on the kit or finished board will be slightly different, so hereby declare!
Friends who purchase the finished board must strictly follow the installation on the drawing or the PCB board when assembling and debugging. The welding connection is correct and the power can work.
