I have a pair of these Genalex GL GZ34 (aka 5AR4) rectifiers in my PrimaLuna Dialogue Premium PreAmp along with some Genalex GL 12AU7s and a pair of Mazda CIFTE 12AU7s... This combination along with a McIntosh MC152 Amp and a pair of Martin Logan ESLs are very sweet...
"In space no one can hear your cryo tubes scream." ;^)
I know that this is an old post but in case someone still reads it (like me) I have to ask this: cyro freezes everything in the tube and then comes back to a normal temperature. So then the tube goes into its circuit and gets heated. So can someone who is better trained than me (which is about 99% of the people out there) tell me just how they can say for sure that the cyro is working? Did anyone hear the tube before the cryo and then the same tube after? If so, how does the cryo rearrange the molecular structure and keep it the same once the tube heats up for the heat will affect the molecular structure the same as the extreme cold, will it not? When NASA does their cyro on the parts they use, are those parts exposed to very high heat over and over again such as a tube in a circuit or are they a "one and done" application?
Curious as to thoughts / explanations...and thanks...
You guys are so mean. A little humillity about the subject on both sides might be in order. I'm willing to concede to either side with some relevent data. I never saw a technical explaination for or against cryo treatment. Everything said was hearsay and anecdotal and none of it convincing either way.
Give me the physics please. After all heating steel and quenching quickly adds strength why is it so hard to believe that something you may not happen to know might happen in the other direction. Approaching absolute zero transforms many materials into super conducting states. Cryo is far colder than -40 F. Cryo is closer to AbZero than -40 F
BTW When I say say heating steel I'm not talking about leaving it in your barn over the summer.
I wish @geoffait would come back I want to hit him up for some of those Nasa tubes 😉
