Hi.These are two total different animals, my friend.
Cryoenics is a branch of physics (or engineering) that studies the production of very low temperatures (below -150C, or -238F or 123K) & the behaviour of materials at those temperaturs. This deep-freeze started well back in WWII & was first commercialized in 1966 by Ed Busch.
The National Institute of Standards & Technologies defined this lowly -180C basing on the boiling point of permanent gass (helium, hydrogen, nein,nitrogen, oxygen & normal air) being below -180C.
As compared to Freon refrigerants, HsS having boiling points above -180C.Applying cryo science to electroncs, like amp valves etc. can be called cygrotronics.
By freezing it in the frige freezer is NOT cryoing, it is, IMO, a tweak.
Does this tweak work??? I went through this tweak myself hoping that such deep freeze MIGHT help to some extent improve the sonics of the parts, borrowing the cryogenic concept of metal structure stress improvement.
I tried such so called deep freeze of my tube, intersconnects & the likes in my freezer down to -30C for a couple of days & warm them up slowly in a couple of days. A pretty tedeous & boring process.
I found the sonic improvement, if any, was pretty subtle provided that you have a very revealing sound system.
Again, please don't blind us with science which does not apply to this tweak.
