SONY EQ-2 Junk Phono Equalizer

The SONY M6A CARTRIDGE EQUALIZER is a high-quality equalizer that provides stereo output with an auto-off function.

I was using it until recently, but it developed a malfunction where it turns off after about 10 minutes, even when powered on.

There is no rust or other damage in the battery compartment.
I am listing it in the hope that someone who can repair it might be interested.
If you are interested, please consider it.

- Brand: SONY
- Model: EQ-2 CARTRIDGE EQUALIZER
- Connection Type: RCA Output
- Power: Equipped with AUTO OFF function
- Output Channels: Stereo (L/R)

Thank you for looking.
