Silvertone 12ax7a Tube Jack White ZZ Top Black Keys

Every little piece of gear counts when trying to re-create a famous sound. Here is an authentic Sears Silvertone tube! Vintage Silvertone amps have been used by Jack White, Billy Gibbons, The Black Keys, Mastadon and more. Tubes can change your sound, right? I have played guitar for 50 years. I hear it. Stevie Ray Vaughn heard it. Silvertone tubes were made by Amperex(Bugle Boy, Mullard), RCA, GE. The marking on this tube is not RCA or GE, so I can safely guess it is Amperex( made in Holland). I have only found one of these with the red silkscreen online for $75 I will part with it for $45. Tone matters for thoughtful musicians. Call or text me George
