5R4GY/WGA/WGB tubes are often unaffectionately referred to as potato mashers because of their superficial resemblance‎ to the kitchen tool of the same name. OK, I admit the look is an acquired taste but one thing is certain: Chatham was a division of Tung-Sol and nobody built higher quality vacuum tubes than Tung-Sol.
