Description
The 6N2P-ER tube are a replacement for 12AX7 in any typical amp application, but they have 6.3V heater voltage and would need a different wiring than stock 12AX7’s. Designed to amplify low frequency voltage. It is used in pre-amplification cascades on resistances.
Near equivalent: 12AX7, ECC83
E – the letter characterizing the increased durability of the tube;
R – characterizing the increased reliability of the tube.

I am from Romania and I bought 10 types of vacuum tubes (including 6N2P-ER) from this seller and a total of 26 tubes. All the tubes correspond to the description, and the seller also offered me a discount of $24 for the value of the entire shopping basket.
I have been communicating with this seller frequently for one year and he has been helpful for me in shipping other similar products from Russia.
He is also an experienced Ebay seller.
