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!

The lack of markings would eliminate GE or RCA as a manufacturer, as those marks generally stick around.   Your 12AU7 looks to be a Sylvania.
