FYI: These tubes are measured in autobias mode according the manufacturer data sheet.More information you find at the end of this describtion

1 x tube   ECC802s 12AU7WA  Telefunken

DC U7211201k = 1971


The test result is perfect

Measured in autobias mode
Emission = Gm 2,230+2,200  (new = 2,200mA/V >1,800...2,600< )  
Anode current Ia:  10,5mA + 10,6mA (100% = 10,5mA ±1,8mA)

Please do not confuse "S / gm" with "Ia". 
Only the value s / gm says something about the emission and thus the life time
Measuring device used: RoeTestV11.

Measurement mode: Autobias as specified by the manufacturer.
In autobias mode the tube is measured with a constant anode current. This corresponds to the application in the device.
Note: Most tubes offered on ebay are tested with a fixed grid bias voltage. Such a measurement contains a general system error. The desired result in the application is therefore purely random.
