MMCF10 Feedback Attenuating Phono Amplifier MM Phono Preamp Board

Specificaitons:

Contains four BB company op amp OPA604 (single op amp)

PCB size: 93*100*1.6 1OZ copper, spray tin, FR4 grade A sheet

MMCF10 is RIAA compliant

Design Highlights:

1. The power supply is designed with a small capacitor array, equipped with a secondary voltage regulator, and the low ripple is more clear.

2. Each channel uses two single op amps for amplification without interference

3. Feedback attenuation type, the speed will not be too fast

Recommended input voltage: AC 18-0-18V, no less than 100mA current

It is recommended to use the R cow with copper foil shielding layer

Gain: 41DB @1KHz

Input Impedance: 47K

Kit configuration:

MMCF10 kit, use:

A. Vishay BYV27 smooth rectifier tube with beautiful sound

B. Electrolytic capacitors form a filter capacitor array, with low power supply internal resistance and fast dynamic response

C. ST 18-15 three-terminal voltage stabilizer tube builds a secondary voltage stabilized power supply, with strong anti-interference ability of mains

D. Supporting 4 OPA134 op amps of BB company

E, WIMA, EVOX, PHI, ERO brand electrodeless capacitor sound calibration

F. The feedback capacitor is Nichicon FINE GODE (FG) series
