On offer we have a beautiful matched pair of white print Brimar 12AU7/ ECC82.    These devices present with superb matching both within the envelope and inter device.

These devices have tested on our AVO VCM163 valve tester as having 100% emission with very close matching for each triode section within the envelope.

V3: Section 1: Ia = 10.0 mA; gm = 2.2 mA/V

V3: Section 2: Ia = 10.0 mA; gm = 2.2 mA/V

 

V4: Section 1: Ia =10.0 mA; gm = 2.0 mA/V

V4: Section 2: Ia = 9.5 mA; gm = 1.9 mA/V

 

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

Ia = 10 mA; gm = 2.2 mA/V

As you can see, this result show a really  strong matched pair of valves with good matching of each triode section within each envelope.
