Title: Question about 12au7
Post by: dro007 on November 06, 2017, 02:19:06 AM

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.
