This is the Goken Lab GK05EcR phono equalizer. I purchased it new in 2015 and used it, but I haven't been using it since I replaced my equipment, so I'm putting it up for sale. I checked the operation before listing it. The included accessory is an AC adapter. There are small scratches and minor dents from use (photos 3-5). Please take a look at the photos and understand that this is a used item before purchasing. Regarding the specifications, please refer to the following information on the Goken Lab website: > For MM cartridges * Input impedance 47KΩ Input capacitance 100pF > Copper foil PPS & PP * CR type > ・Clear sound quality, especially suitable for music with a strong sense of rhythm, such as JAZZ. > ・MC cartridges can also be enjoyed via a transformer. > ・Gain can be switched between 35dB (for high-output cartridges) and 45dB. > Aluminum case Size 120w, 25h, 120d Thank you.
