Matched Pair of original

Tesla ECC88

great sounding ECC88 6922 6DJ8 E88CC family tubes

Tubes are probably new, not used, tested NOS. same code.
Made in Chechoslovakia in NOVEMBER 1981 according to "VR" code
come from large military stock, no boxes
frame grid, box anodes with the white metal shield
these are 37 coded famous TRINEC plant Czechoslovakia
there is almost always the possibility that the tubes were used for a while, but I'm pretty sure that the tubes were never used, NOS
test strong, look great, came from huge military stock.

almost perfectly balanced and matched,  high emission
 test results:
tube1 - 20mA/20mA
tube2 - 21mA/20mA
where new tubes should test 14mA
Same code "VR" November 1981
Tested in High End preamps. Great for audio.
price is for the pair (2 tubes)
sorry no individual boxes this time
I always send the tubes by priority registered mail with tracking number within hours after receiving payment
