The tube(s) pictured will be the one you receive. Real world tests were conducted on my u-Tracer testing unit. The results match quite accurately to tests performed on my military grade TV-7B/U unit, but the u-Tracer results will give you a better idea how the tube may perform within your application. The tube(s) were also tested for shorts, gas, and emissions.

Derivative Definitions:
Ra = Plate Resistance
gm = Transconductance (or mutual conductance)
mu = Amplification factor

Nom = Nominal ratings for tube type. (i.e. Nominal readings are considered NOS-like) 

If you would like a different test reading either from my TV-7B/U or B&K 707 or have any other questions regarding this listing, just let me know.

Thanks for looking!
