I know of a local guy who does the cryo thing. His name is Bill Perkins and he's the man behind Pearl Tubes, a company which specializes in rebranding tubes after freezing them, amongst other things. Bill has lots of test equipment including devices which measure tube microphony. I've seen this equipment when I had him test some tubes for me. I do not want to misquote Bill, but he basically stated that if you take a tube, measure the microphony, then freeze it, and measure it again, there is a sig difference. http://db.audioasylum.com/cgi/m.pl?forum=tweaks&n=14981&highlight=Cryo&r=&session= Intresting read,but it did not state weather these measurements were for positive improvements |
