D dro007 New member Nov 6, 2017 #1 Hi, I purchased a Crack in april, and I wondered if anyone could help me identify the 12au7 tube that came with it. The name or anything written seems to be smudged off. The picture should be attached Thanks in advance! Daniel Rød Newbie from Norway Attachments IMG_20171106_141225.jpg 3 MB · Views: 29
