MMCF10 Hifi LP Phonograph MM Amplifier Kit / RIAA Phono Preamplifier Board / Phono Amplifier PCB
PCB Size: 93*100*1.6mm
Recommend works voltage: AC18V-0-AC18V (transformer power need above 10VA)
Gain: 41DB @ 1KHz
Input impedance: 47K
This MM Phono preamplifier board, sound is very good, warm, dynamic, clear, sophisticated, excellent resolution.
Design highlights:
1, the power supply using a small capacitor array design, with two regulators, low ripple more clear
2, using 2pcs Single opamp (BB OPA134) for each channel , do not interfere
3, feedback attenuation, the speed will not be too fast.
