Dual-OP Phono Amplifier(MM) RIAA DIY Kit Project

(1)Tech highlights:
All-in-one design, single-point grounding, ground resistance is close to the 0.02 ohm resistance value, low noisedesign

Dual op amp design, can replace different op amps to present different sound performance.

PCB is Small mini
Input Resistance: 47K
Gain: 48DB(1KHz)
THD:0.05%(1KHz)
RIAA
PCB SIZE: 77x70x1.6mm 1oz Cu, HASL with lead.
Power requirements: Best: AC15-0-15V@0.4A

(2)Product configuration:
DIY kit: Contains the PCB and the components needed on the PCB, but does not include the power transformer .

Finished board: Based on the well-tested board on the standard version kit, we verified all key points' voltage, and used the signal generator and oscilloscope for analog waveform double verification. We will not use this board for listening test.

All finished pcbs are all carefully hand-soldered and fully tests, so the price is higher and less cost performance. Price-sensitive consumers but with have DIY ability are recommended to choose the kit.

(3)Schematic & key point of debugging:
PCB comes with component parameters for easy installation.

We only refer the schematic of the amplification part of the circuit. If you need full circuit parameter, please read the component value with the PCB by yourself; we do not provide additionally.

please keep test point voltage close enough to it, +-20% is also permitted
