Default 6N6P vs. 6N6P-I

guys - i am not smart here...
i have came accross two different version of 6N6P tube...
one is without "-I" and the other has its full name 6N6P-I.... it seems that the one with the "-I" is made to work in a impulse mode....

the question is this - can i use 6N6P-I the same way as 6N6P tube??... are they the same or are there any differences??... what are the differences??..... i don't get it....
thanks in advance.... many regards
daniel

Hi,

According to Lampizator the best one for audio is the 6N6P.

They are basically the same tube, but characteriozed differently. The I variant is for impulse operation so it's curves indicate positive grid voltages. Because of this it is also not tested for microphonics and noise as these parameters are of no importance for audio. As a result, the i variant MAY be as good as the regular variant but this will vary between samples greatly. If you want to be sure, use the regular one.

"H" for N, Double Triode.
"П" for P or Pi. Small Glass Envelope.
"И" for I, Pulsed operation

Perhaps sometimes Pi might be mistranslated PI???

I believe 6N6P-I later was renamed to 6N30P

i have been searching on the net.....
ilimzn was right - as usual

"I" version is for pulse operation - and also it is 500 hours variation of the tube.... the one without the "I" is the one that can be used 2000 hours....
it seems that "I" one is no good for me.... to bad.... i will play with it when i catch the time - to see if those two will be good in line... and in future i will try to find only plain 6N6P versions......


thanks guys.....

Why are you guys denigrating the 6N30P (by denigrating the 6N6P-I)? The 6N30P usually sells for a premium, and gets a lot of raving reviews.

I'm glad you said that leadbelly as I have some in the post bought off ebay for a very good price.

Real value and marked value are quite different things.

Fair enough, I'm willing to believe the 6N30P hype is just that, but can you back it up?
