General:
Here is something we don't see every day, French-made Vacuum tubes!

These RT 12AX7 tubes are sought after for their excellent build quality and tone. 

Both tubes are testing strong with very good triode balance. Perfect for preamps that share their left and right channels in a single tube such at the Audio Research SP-3, and V3 / V6 positions in the Marantz 7 and original McIntosh C22.

This pair of tubes comes with original boxes as shown in our listing photos.

SkyFi Cosmetic Notes:
Boxes show shelf wear. Otherwise great shape.

SkyFi Technical Notes:
6941 and 6942 date codes (Very Close date codes).

Both tubes were tested on our modern and professional Amplitrex AT-1000 tube tester.
