6J10P-ER

The Soviet 6J10P-ER (6Zh10P-ER , 6Ж10П-ЕР rus.) vacuum tube is a high-frequency miniature pentode with increased durability and reliability, a short anode-grid characteristic, and dual-grid control. It is designed for use in broadband high-frequency voltage amplification circuits. It has an indirectly heated oxide cathode. Base: 9-pin (Noval / B9A / RSh8).

E – the letter characterizing the increased durability of the tube;
R – characterizing the increased reliability of the tube.
