The line is compatible with the preamp and the phono amplifier. The phono amplifier part can be controlled independently.
Solder the tested finished motherboard. To reach the finished machine, the customer needs to configure a transformer, potentiometer, connector, chassis...
The circuit diagram is derived from the Kondo (audionote) M77 model of 500,000 RMB.
Tube model 6X4 (ez90) one 12AY7 (6072) eight.
Please refer to the circuit diagram for the parameters of the transformer and other parts
In view of the current high mains power, the 9 filter resistors in the actual product are adjusted from 2k to 2.4k.
Adopt 2.4mm double-sided gold-plated PCB circuit board. Most of the resistors are DALE and Philips instrument-grade precision resistors.
The signal channels all use TRW and GOOD-ALL bakelite-sealed coupling capacitors, and the old gold-plated bladder seat.
Designed to independently turn off the phono-amp function, 4-way to the relay switching signal, reserved for self-adding choke play.
The size of the pcb board is 220x290x2.4mm. The board is marked with the screw mounting hole size.
The standard 430mm width chassis with 3 knobs on the front panel and the internal height of 7cm are suitable for installing this kit.
To reach the finished machine, the user needs to configure the electronic tube, transformer, connector, and casing...This store does not sell these items, and does not accept the final assembly business of the finished machine.
