I second the idea of using Cryogenics International for your tubes, cables, interconnects, and power cords.
.
Your tubes won't probably weigh enough to cover their $ 75.00 minimum. Throw in a power cord, interconnects, or Symposium Rollerblocks (and some packs of new Razor Blades, you will be stunned how long your razor blades will last).
.
Keep in mind that you will have to re-break in any wires you get cryoed. It took over 200 hours for my speaker cables to break in again (at full playing volume), but in the end, it has been quite a sonic upgrade of my system.

Charles Beresford at Cryogenics International is a gem to work with.
