The 3886 power amplifier was produced, and the pre-level was set to 6N2. From the entire plan to the schematic selection and drawing, PCB, electronics, structure production, and debugging and installation of the whole machine, it was finally completed. The circuits used are familiar to everyone, so I wo n’t go into details here, so I will understand it by looking at the pictures.
Electronic part production
1. 6N2 pre-stage
The schematic diagram uses "no gall" drawings, as follows:
The PCB is drawn by itself, and the PCB board is produced by thermal transfer (the PCB production process will be described in detail in section 3886):
After the pre-stage production is completed, the capacitors and resistors are all very common materials, especially the coupling output capacitors, and the most common CBB is used first.
