There's a much bigger article to come, complete with photos...
I recently cryogenically treated a Sovtek ECC83 tube (of which I have two) by sticking it in a styrofoam insulated box for about 15 minutes; the bottom of the box had been covered in liquid nitrogen. I dropped in the tube in an aluminum mesh bag-like thing (to keep the pieces together in case it shattered) and closed the lid, then waited until the LN2 had boiled off.
I then marked the bottom of the tube with a red permanent marker.
The results? While the other Sovtek has a lot more use (judging by the silver deposits on the glass), the other one has a lot more life - it's still a Sterile Sovtek, but the bass is deeper and meatier, and the midrange is more magical. There also might be less distortion...
(of course, I gave the treated Sovtek about an hour to warm up vs. 5 minutes for the non-treated tube)
More to come once my webserver is up.
