I have a Carvin x100b tube half stack. I replaced the tubes with these and also 4 same brand EL34. All I can say is wow. My amp is so clear and loud. I mean in the house I can only go up to 2 and it is loud. Treble end is crystal clear and the bass end is nice and crisp and well pronounced.... Mid range is strong and clear as a bell.... I will buy them again when I need tubes again.
