A small unbranded tube preamplifier built around a 6J3 vacuum tube, meant to sit between a line-level source and a power amp or powered speakers. It takes low-level inputs from a phone, CD player, computer, TV or MP3 player and adds the mild harmonic warmth and gain that tube stages are known for. It is a budget DIY and hobbyist part, not a full amplifier, so it suits tinkerers and desktop listeners rather than anyone wanting a finished hi-fi component. Compared with branded tube preamps it offers far less documentation, no remote, no tone controls and a plastic case.
