FS: Two Lorenz 12AT7/ECC81 Tubes
Before Christmas I was lucky enough to have won a lot of Euro 12AT7 tubes. Didn't think I'd sell 'em, but I lost my job and had to pay for my final semester of school, and this has left me pretty strapped for cash, so here are some of my tubes! If my prices are out of line, let me know.

Tube 1: $23
Tube 2: $22

Tested on my calibrated Eico 667, modded to measure plate current (with a Fluke 27/FM, current is DC), and using a testing configuration developed by Conrad Hoffman on the Audiokarma forums. You can find the discussion thread on how the testing data was corrected here: 12AT7 Testing Settings -- They Change the Voltages?! - Home Audio Stereo Discussion Forums

The writing on the boxes might not make much sense, but it's how I personally categorize my tubes. Some tubes will have stickers or writing on them with alternate data; this has been superseded by the data on the boxes.

No one likes copper grid supports and a getter support that captures both micas?

From before the ITT/Lorenz era!

I'm surprised no one with an SSE is interested in trying some of your tubes..
