6f2 - 6n1???

[fauxpas]

Sorry guys and girls, I know I bore you all with my newb questions...

After having the powertube worries recently, I decided to look up and buy replacement tubes. The amp was listed as having 6F2 (ECF82) preamp tubes, but the print on the tubes does not show either of those designations, but is instead printed with 6N1.

All the sites I visit list the 6N1 and 6F2 as different tubes and never group them together as cross-usable...

Are they indeed exchangeable?

Simply: no. One is a double triode, the other a triode-pentode combo.

So I go with the tube type in the amp at the moment, not the one listed?

I've messaged the seller of the amp to try and work out what's what.

The triode-pentode looks like Russian 6F1P

Looks like 6F2P, which is what it is.

I don't remember 6F2P tubes, I never saw them, never heard of them. I remember 6F1P, 6F3P, 6F4P, 6F5P.

Where they were used in?

So do I go 6N1 or 6F2? What will happen if I use the wrong one?

I'll take a pick of the actual tube in question.

I don't really understand what the problem is? If the original one works, use the same type.
6F2 is not the 6F2P, as far as I know, there isno 6F2P. The 6F2 in the pic is chinese.

I think wavebourn's reference to 6F2P was regarding the pics in my 1st post with pics off the audiotriodes website.

In my pic, it shows the tube with 6N1-J printed on it. So I should go with what is working in the amp and not what was listed in the literature for the amp, which is 6F2(ECF82).

ECF82 = 6BL8 = 6F1P

So if Chinese 6F2 is ECF82 it means it is an equivalent of 6F1P (triode-pentode), where Chinese 6N1 is equivalent of 6N1P (double triode)

Did we answer your question?
