Chuck	Re: Make that fender sound warm Peter, People have been freezing steels for a couple of decades. The cryo tube thing is not new either. Probably one of the more recent developements though. But I do know that while carbon steels are structurally benefitted by cryo treatment, there is no such benefit to lower carbon steels, and niether show improved conductivity. So, to take this to the microscope, very little of the metals used in manufacture for tubes is of the high carbon type (with the possible exception of the filament). Not only that, tubes aren't transducers. There are ideally no moving parts in a tube. So structural improvement would be of no use to to the audio properties. And like I mentioned, there is almost no steel in a tube that benefits much from the cryo treatment. Perhaps there would be a minor long term improvement as far as a tubes tendancy to become microphonic. But other than that I can't believe that there is any reason to freeze a tube. I mean, If there is no change electrically, only minor improvements structurally and tubes are not mechanical in function anyway, where is the improvement in tone comming from? It's just more mojo speak. Like special power cables and placing crystals on your hi fi. Chuck
