This is a pair of 6J1P high-frequency pentode vacuum tubes for tube headphone preamps and other audio equipment. The 6J1P is equivalent to the EF95, 6F32 and 6AK5. The tube is made of glass.
The first grid is wound with wire made of gold and alloy, and the lifting grid is made of copper. The tubes give a clean, warm, natural sound with low noise. The sound field is fuller and wider, the treble is smoother, and the bass is clearer and more pronounced.
Using the wrong type of tube as a replacement may damage the equipment. If you are unsure whether the 6J1 suits your audio equipment, consult the equipment manufacturer.
