This is a 6J1 (6J1P-EV) high-frequency pentode vacuum tube for audio equipment. It is equivalent to the EF95, 6F32 and 6AK5. The first grid is wound with gold and alloy wire, and the lifting grid is made of copper.
The tube is made for a clean, warm, natural sound with low noise. It is meant to give a wider sound field, smoother treble and clearer bass.
Using the wrong type of tube may damage it. If you are unsure whether this tube can replace the one in your equipment, check with the equipment's manufacturer first.
