For this reason, I have never used these devices as I figured that was a possibility and cannot see the value in them.
    Like this, Davey?

    Well, kinda, but luckily the 'lava' did not flow down all the way to the socket. And it was a relatively cheap Russian 6N1P tube on my ARC VS 110.

    Next model ARC VS 115 they now supplied a black o-ring damper on the 6H30 tube.

    I found a store selling these orange rings that specified a very high temperature threshold before melting, and it said these were really made for hot vacuum tubes, so I took a chance. Placing them on the tube gives some overall stability in the soundstage and things are more focused, in my observation. It is not night and day, and probably it can be system dependent even. My only reservation is that sliding these tight rings into my old old tubes might eventually rub off the precious print work in the tubes.I don't really like looking at plain glass.

    Yes Phil, that's pretty much what it looked like ( in your first photo)...only worse!! Personally, having heard about this from several other a'philes who have had varying bad experiences with the same thing, I am leaving all of my tubes..bare.
    I think ARC supplies the rings on their newer gear...which surprises me a little as I know of two guys who had problems with the dreaded 'melt' even with the factory rings!

    Davey,

    I have to add just for the record on this post that I have owned 5 different ARC preamplifiers with tubes (SP9, SP14, LS25 MKII, Ref5 SE, and now the Ref 10. I have NEVER had an issue with the Audio Research supplied tube damping rings melting. I did try them removed from the LS25 MKII but reinstalled them after comparing with and without.

    This is an interesting tube I got not long ago. Amperex Bugle Boy 12AX7 marked Made in Holland but the date code starting with a D connotes it was actually German made. It has a rare 'foil getter' on a horseshoe support. It does not sound as full and lush as the Mullard but is very fast on top and tight on the bottom. Before I had installed the CS footer on my system, this tube would sound too 'bland' for my taste and also quite lean. I used it as the first gain stage in my Minimax phono stage, with the 1950s pair of Brimars on the second stage. After I installed the CS footers on my amp, preamp, and phono stage, the sound with this combination worked fantastically, so much so that in four months since then, I have not had the itch to remove this combination. There is now body in the instruments with great balance from top to bottom. The wonders of the footers, and tubes.
