How cool is tube deep cooling?

Hi, I mean cryogenic treatment. Source is here

IF it really DID do anything, Don't you think that tubes and other elect. parts intended for critical and military applications would have this treatment done as a normal proceedure to improve the performance?

Just another High-End Money Extraction Tool, along with the silver power cables and crystal-stones!

Just marketing cr-ap...Dont fall for it!

Igormac, do a search for cryogenic treatment, it has been discussed to death here already.

Of course, that's part of the point. Anyway, a lot of people (inc me) knows that old tubes sounds much better than same new ones.
We have not yet sat. explanation of that, have u?

Secondly, I know russian company which made similar envestigations and they said that results was really great.

That's why I'm asking do anybody hear more about the topic.

To death! Sorry, I'll try again.

cyro treatment what a bunch of who ha al cyro treatment of metals does is releive minute residual stress's well unless it's always submerged in ln2 then you reduce resistance but this property is only exhibited in certian metals usually with a high room temp resistance.

If anything cryo treating could trash a tube if it's filament in thorated tungsten because at those temps it would be so brittle that you couldn't move it tell it warmed up.

Can you say "Snake oil"?

I'm considering it for my Grandmother.

As the Resident Skeptic, I would say, "Not so fast." This may indeed be utter BS, but IMO, it's worth looking at since it passes three of my personal skeptical filters:

1. Testimonial evidence from people I respect.

2. A plausible physical mechanism.

3. A way to objectively and quantitatively test that mechanism.

Most snake oil can't get past 1, and none can get past 2 and 3. I leave aside questions of audibility, I'm just talking about claimed measurable changes. I'd like to see the measurements, but would even more like to do the measurements.

"Not so fast."

None of my tubes have been cryo-treated so I won't judge but I agree with SY there is plenty of evidence that points towards benefits.

Most if not all of the negative commentaries come from people that haven't done any research let alone heard a cryo-treated tube.... That says something

Igormak, I'ld definitely give it a try and please report here with your findings
