Vacuum Tube Phono Equalizer Fosi PHONO BOX X2
Product Details
This is the Fosi Audio PHONO BOX X2 vacuum tube phono equalizer.
I purchased this about a year and a half ago for external use because I didn't like the sound of the built-in phono equalizer in my amplifier. I used it for about an hour per week.
I am selling it because it is no longer needed due to an amplifier upgrade.
It is used to connect a record player to an amplifier that does not have a PHONO (record player) input.
It can be connected to a regular line input or AUX terminal. I was satisfied with the sound, as it was considerably better than the built-in one.
- Phono equalizer for MM cartridges
- Amplification level switchable in 3 stages
- Line input via 3.5mm mini-plug
(Can connect smartphones, media players, etc.)
- Accessories: AC adapter, 2 vacuum tubes, mini-plug โ RCA cable, instruction manual
*RCA pin cable is not included.
This is a used item, so please expect signs of use and minor scratches. Please check the photos for details.
Thank you for looking.
