Manufactured by Sylvania Electricfor THE UNITED STATES AIR FORCE IS BLACK-GLASS BETTER? ..."The coating on the plates is used to dissipate heat from the tube components. At one point it was only made with nickel making the finished color black, during WWII once nickel became short, aluminum was used instead making the finished color dark grey. This became the adopted manufacturing process until the early 1950's or so.So, as you say the plate color gives us a a good marker of when the tube was made, rather than a direct indication of the sound quality. Since the black plate process is older, those tubes are becoming more scarce, so more costly.".. Why buy to from sellers who don't even test or show you the real test results?
