EICO's best tube tester, a "Transconductance" tester. The Transconductance test is somewhat similar to a Mutual Conductance tester but uses AC voltages instead of DC and does not provide a direct Gm reading in Micromhos. The test provides the "Merit" of the tube under test with a percentage reading of the expected value.

I strongly disagree with this, thinking the EL34 is one of the most musical tubes out there, walking a fine line between a triode romance and warmth, and the more dynamic sound of the 6550. The Shuguang "B" version of the EL34 is the stock tube in countless amplifiers and has been labeled Ruby, Valve Art, and who know what else. My recommendation for home testing: get a simple Emission tester like a B&K DYNA-JET, Heathkit, Eico or other NON-Gm tester. They are simple to use, stable, accurate and relate well to the life remaining in your tubes. Buy your tubes from someone who certifies their specs to be proper when new.
