This is a pair of 6J1 (6J1P-EV) high-frequency pentode vacuum tubes for headphone preamplifier use. The 6J1 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 produce a clean, warm, natural sound with low noise. They are built for high reliability and stability.
Installing the wrong type of tube can damage it. If you are unsure whether the 6J1 can replace the tube in your audio equipment, check with the equipment's manufacturer first.
