Telefunken 12AX7/ECC83 60s - Excellent

Up for sale is a matched quad of genuine Telefunken 12AX7 / ECC83 tubes.

Key details:

•  Long gray smooth plates

•  Authentic diamond marks molded into the glass bottoms (all four tubes)

•  Made in West Germany

•  Original GAP/R Computor Tube labeling

•  Clean pins, good print, excellent overall cosmetic condition

Test results on a Precision 10-12 tube tester (both sections of each dual triode):

Tube 1: 78/100 & 78/100

Tube 2: 80/100 & 78/100

Tube 3: 76/100 & 78/100

Tube 4: 76/100 & 78/100

These are strong, consistent readings. On the Precision 10-12, solid NOS 12AX7s typically land in the mid-60s range, so these test well above average and should have plenty of life remaining.

These are the classic long smooth-plate Telefunkens that many consider among the best-sounding 12AX7s ever made — detailed, smooth, low noise, and highly regarded for both hi-fi preamps and guitar amplifiers.
