DIY Hifi MM RIAA Turntables Ear834 Tube Phono Amplifier board panel 12AX7/ECC83

Description

Details：
Power supply requirement: Secondary voltage requirements AC230 ~ AC280v, greater than 30mA, 6.3V greater than 2A.
PCB size: 130x285mm
tube model: SHUGUANG 12AX7 /JJ ECC83S
TIPS：
Because everytime purchase of components may different, so the objects may have difference with pictures, but the quality and performance is the same.
This board need you have electronic technology and detectability,it's special designed for Hi-End HiFi Audiophile.
Note:
The DIY Kit is a pcb set of transistor resistor.
The Assembled Board has more capacitors than the DIY Kit.
To reach the final machine, the user needs to reset the configuration of the tube transformer connector housing.....This shop does not sell these things.
DIY Kit includes (one double-sided immersion gold pcb board, 37 imported high-precision resistors, one filament rectifier bridge, four high-speed rectifiers, one power adjustment tube, four zener diodes, and three 9-pin tube holders ) (Different expected parts or slightly different from the picture)
(The secondary voltage of the configuration transformer requires that the range of high voltage group ac230 to 280v is greater than 30ma, and 6.3v is greater than 2a)
pcb size 130x285mm
Note：
if choose Diy Kit ，all parts need buyer to solder ！
（not included 3pcs tubes）
if choose Assembled Board ，have tested it well ！（not included 3pcs tubes）
