Let’s talk about cryogenics and tubes
Awhile back I wrote and article titled “Cryogenics Treatment of Tubes: An Engineer’s Perspective“. Like politics and religion it’s, ironically, one of those topics that people can get pretty hot under the collar about and I have to admit to being skeptical, even cynical of the value of the process when applied to vacuum tubes to improve their audio performance. But I try to keep and open mind, hence this post; if you’ve worked in the tube manufacture business, perhaps you’re an ex-employee of Mullard, a materials scientist, physicist or worked on the assembly line then do feel free to chip and have your say. Any guitarists and recording engineers with an opinion are also welcome to contribute their views on cryo-treated tubes—this is the place to do it!
