This pair of well matched (6.6%) 7062 tubes. Both tubes are perfectly balanced as well. The very rare pinched waist style of tube is known for very low microphonics. Rated for 10,000 hour heater life. The 7062 is an industrial version of the 12AT7 and it has a D getter with a foil strip. The Heerlen factory code so famous for great tubes is clearly visible in the pictures.

These tubes are in their original JAN boxes and were imported by CEI in compliance with US military specs. I purchased them from reverb recently and have only used them for about 1 hour to test. Sound amazing. I paid $200+shipping, but have no need for them right now.

Tubes as better than NOS and they came out as follows:

8875/8875
9500/9500
