MULLARD EL34 6CA7 Matched Quad Set - Electron Tubes - Made in Russia

Boxed Mullard EL34 Matched Quad set (4 Tubes). They were tested and matched at the factory. Factory test results are on the stickers at the end of each box.

All 4 tubes were then tested and certified by Upscale Audio of Southern California.  Tubes were 72 hour burned in and ratings marked on each box.Currently tested and all test strong on my home testing unit.  These are plug and play ready to go.  Used briefly in an audiophile tube stereo amplifier and then swapped out for other brands, these have seen very limited use.
