6SN7 tubes in the SEX

[Maxwell_E]

I've been reading all through the SEX section of the Forum and I've found that several people are using 6SN7 tubes in the amp, while I have 6DN7. Curious, I pulled up some data sheets and noticed the two tubes were pretty much identical besides the capacitance rating for the second triode. Is the 6SN7 a direct drop in for a stock SEX, or would some fiddling about have to be done before-hand?

Data sheets:

No, The 6DN7 is 2 tubes in one bottle and they are not at all the same.

1 section, used as the first stage voltage amplifier, is very much like ½ of a 6SN7, either half. The 6SN7 being 2 tubes of the same type in the same bottle.

The other half of the 6DN7 is a power tube. Take another look at the 6DN7 sheet and compare the specs of section 1 to section 2…John

edit: were you maybe looking at the Foreplay 6SN7 thread?

It may have been, but I could have swore they were talking about the 6SN7. And i see what you mean now, thanks.
