This product is not handled by official distributors in Japan. I received it from someone in the UK several years ago. Operation has been confirmed, and the vacuum tubes can be replaced to your liking (the original Project tubes are also quite good). There is a tear in part of the outer box (see image 8, I have intentionally not repaired it with tape, etc.). Excerpt from the official Project product description: ● Innovative compact phono preamplifier with vacuum tube output and high-end sound ● Fully discrete circuit design, without using any op-amps ● Dual-mono circuit for optimized channel separation ● Compatible with MM and MC cartridges, with multiple gain settings selectable from the front panel. ● Input impedance can be adjusted in 5 steps.
