Condition: used This auction is for a vintage and original Tube Tester Mercury 204 in reasonable condition and. Power turn on and meter is stable. This is An emission checker tests for shorts & cathode (or filament) emission only. The meter reading gives a good-bad reading by virtually tying all the elements of a vacuum tube together (except the cathode & heater) and testing the tube for cathode emission by subjecting it to test as a diode (or rectifier). An emission checker will basically tell you whether a tube is usable or not and give you an indication how strong is the cathode emission. however is good testing for shorts and leakage. I have post few picture with using same 5U4GT tube on different tubes tester so you will get a good idea of the condition and the reading which is very close however this usually doesn't happen because they are complete different testers a Hickok vs Mercury that is a no way. I did try a 12AX7 and is not reading same there is a 15% off.
