Elekit PS-3250 Phono Equalizer Kit
The Elekit PS-3250 is a MM/MC compatible stereo phono stage kit. Offering super low noise and clean RIAA-equalized line-level signal. You can select between an MM and MC cartridge by a jumper on the PCB. This is a kit; you must populate the PCB with the parts provided.
This can be used with any Pre-Amp or Integrated Amplifier. Not exclusively just amps produced by Elekit.
FEATURES
- Featuring the low-noise NJM2068DD OpAmp.
- The passive electronic parts provided are ±1 % tolerance metal oxide resistors, and ± 2% tolerance film capacitors are adopted to realize small RIAA deviation and low noise.
- A CR design is used for the equaliser circuit, so there is zero deviation in equalization even when OpAmp is exchanged.
- A positive and negative voltage generating circuit is on-board for the power unit, and high-quality sound and wide dynamic range are secured by supplying ±15 V for OpAmp. An external power supply is required (not supplied with the kit). A switch mode power supply is recommended 5Vdc to 12Vdc). The kit does not provide a DC connector.
- POP noise suppressor upon power ON/OFF is on-board. Remember to short if you aren't using a switch.
- The noise level, especially the hum noise, depends largely on the IN/OUT wiring and the grounding location. Therefore, this kit includes an IN/OUT jack and grounding bracket to fix those parts to the PCB.

I would suggest that you fit the op-amp first before you start populating the PCB. Capacitors around them may need some adjustment.
