In Reply to: Cryo'd Tubes Measured! posted by NEAR SOTA on November 25, 2002 at 11:21:51:
I've read about the seemingly dramatic improvements in certain instruments, tools, etc., from cryo treatment, but I'm not so sure freezing tubes is a good idea. The coefficients of contraction/expansion between glass and the tube's metal pins is different. On one hand, if the metal contracts slower than the glass you may microfractures at the metal/glass juncture causing air to be sucked into the tube's vacuum resulting in oxidation of the filament, etc. = tube failure. If the metal contracts faster than the glass, then the junction will again break resulting in air being sucked into the vacuum.While there may be a sonic improvement, tube life will suffer.

Soundstage!I would have thought something that was a danger in doing this,but we are talking about mechanical devices(or constructed components) and not conductors in raw form.Maybe if the components were Cryo's before assembly it would give a longer tube life.
