Ei Yugoslavia ECC83/12AX7 80s/90s - Silver plates

A very nice pair of Silver or Nickel plates from our friends at Ei Yugoslavia. O getter, date codes show 2A1, I can't make out the remainder. All of my tubes are tested for mutual conductance on a Hickok 800a. Gm readings are listed in the photos. 1250 is considered the new reading for each side (12a_7 tubes have two sides that must be checked) of a 12ax7/ecc83 when testing. These tubes test at or above new levels on each side. I have tested these for noise and microphonics in the vibrato channel of a twin reverb. They both sound great. This pair is not matched.

If you are interested in a single instead of the pair, please message me.

If you are in a region out the continental US and are interested in purchasing, please message me to discuss shipping rates, if you want the item and are willing to pay shipping I'm sure we can work something out.

**Your tester may produce different results. I do not accept returns on the premise of another tester's data.** I have checked my tester against other calibrated testers such as TV-7, Maxi-Matcher etc. If your tube has some other unforeseen issue I will be happy to work with you. I sold on the other site for a long time but am moving all of my tube listings to reverb as its cheaper for buyer and seller with more protection for us both.
