2. Allow 1 minute warm up time
3. Test for actual real-life mutual conductance (life) of the tube (including any shorts,gas and leakage)
4. Test for proper gain of the tube (perhaps the single most important test of a preamp tube

accuracy on other tester

If I state any values they are for a guide only.
Two testers are never the same.  So this shows what I get, and what you get may be slightly 10-15% different.
