The Reference 6SN7 Thread

I think I will find a larger cigar box from the cigar shop to store the 6SN7, 6F8G and 6J5s. You can get these for cheap.
Yep, you can get them from Amazon, too. But now that you've started collecting you won't stop, and that means more and more cigar boxes....

You might as well break down and get one of these:

Hard to beat a kitchen
Did you get a solid piece of wood and install socket savers on them?
That would be slick for displaying tubes. I just drilled holes wide enough to accept the tube pins, left a little wood on the bottom so miniature tubes can sit with the big boys and not fall to the floor when I pull them out from time to time to remember what I have in there.

No, as already mentioned the sound should be the same....maybe less chance of back round noise because it is constructed for more rugged use.

If tubes would be the same price I would opt for military version, not sure I would pay a lot extra for them though.
Several arguments may be made.

Military grade: more robust, able to withstand harsh conditions, top echelon picked examples.

Reality: The government creates a specification. The various manufacturers supply their design. Lowest acquisition cost gets the contract. (Unless it's WWII and the government is buying everything available).

I've often thought WWII was one of the best era's in US history to make a fortune. So much needed, so little oversight.

Kind of shocked this tube has not been talked about much in this thread. . .

RFT 6SN7 Welded Plates w/Ceramic Spacers and Dual Foil Cup Getters - Best bass I have heard from a 6SN7 that slams and has detail and texture like no other, mids that are clean and clear with transparency through the roof and vocals that are huge/forward and project out in front, with highs that sparkle and really good staging as well. Overall, it's very well balanced with outstanding dynamics and works extremely well paired up with some Elrog ER300B's, and makes my ZMF's sing to their full potential. The RFT is quite rare and expensive at the moment, but can be found from time to time for around $350 a pair if you are diligent in your search. I love this tube so much I have 5 pairs, and hopefully they last me until a can't hear anymore.

Of note there is a latter version, with a single foil getter and stapled plates and it's does not have the magic of the earlier version, and is not worth the current asking price.

If I could find a pair from a reputable seller I'd buy a pair, but everything I come across comes from Vietnam and I don't know if I can trust that seller...

If I see some I will let you know, and that seller from Vietnam is legit but expensive. That seller has both versions, and I would avoid the latter version from 58'.

He is a bitch but is legit. I bought a pair of Elrogs from him during the great despair amongst many others.

I am even more shocked that ppl dont talk much about using other alternative tubes to replace 6SN7, not to mention a lot of them, NOS, cost around USD10 more or less a piece. Hell, they are not even triode!!! OK, will I get banned now?

There's already a thread for that. :wink: I doubt they can best the RFT, but I am sure that some can hang. Also, the good alternatives cost just as much these days.

I think I know why! :xf_eek:

That seller is not a good one to judge pricing off of, as he is about 50% more expensive than most other dealers. Also, that top pair from 58' is no where near as good as the bottom pair.
