6N11 = 6N1P ?

JoeDJ · 15th May 2011, 10:03 PM

Affer much searching, I'm still a bit confused.
Is a 6N1P a direct replacement for a 6N11?

6N11 spec sheet

http://us.100y.com.tw/pdf_file/6N11.pdf

someone wrote undocumented ecc88 replacement

and this old thread from here popped up

6N1 Chinese tube and others

S=9.5+/-15.7 -- what does it mean?

Edit: I guess I know what does it mean... "Made in China"

I found the spec sheet here 6N2 Vacuum-tube

The main differece I can see is a higher heater current for a 6N1P vs a 6922/6N11.
It's 300 mA for the 6n11 vs 600 mA for the 6n11.

Can that be a concern?

A historical fact is that the 6n1(p) was frequently used (in the past) to upgrade the reception in tube radios.

The clue is that 6n1(p) and 6n11 are both "louder" on HF than 6922. So, if you'd like to replace the tube in a made-for-6n11 circuit, without dulling down the treble, then a probable answer is 6n1(p).

The historical radio reception upgrade used 6np1-ev or similar to replace 6922, and for exactly the same reason.
