About Pearl
Perkins Electro-Acoustic Research Lab, Inc.
Pearl Hifi is a Galgary Canada company led by Bill Perkins who has been conducting research for more than 20 years to improve the operation and life of vacuum tubes. His most renowned product line is that of tubecoolers or tube radiators.
In several scientific studies carried out, among others, on behalf of the US Department of Defense, it has been shown that the life span of tubes can be lengthened considerably by cooling the surrounding glass of the tube. This made the glass less porous and kept the vacuum better if the contamination of the tube was limited.
