Technical and scientific discussion of amps, cables and other topics.

Are you talk about Cryogenics or frige freeze tweaking ?????

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.
