On offer today we have this wonderful black based Mullard ECC35.  Print is  clear good white ink on the envelope.

All pins are bright and corrosion free and the black low loss micanol base is tight to the envelope. This device is ex equipment but has been tested using my AVO VCM 163 valve tester and as you can see from the test data presented below, it gives data for anode current, Ia and mutual conductance gm :-

At Va = 250 V Vg = -4.6 V

Section 1: Ia = 2.5 mA; gm = 1.9 mA/V

Section 2: Ia = 2.4 mA; gm = 1.8 mA/V

The specification for a new/100% emission valve is:

Ia = 2.0 mA; gm = 2.0 mA/V

As you can see, this device shows good emission as well as showing good matching between each triode section within the envelope.
