On offer we have a beautiful matched pair of 18mm, 'long plate' white print STC Brimar 12AU7/ ECC82 carrying identical factory codes of 1413.    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 noninal emission with very close matching for each triode section within the envelope.

A21: Section 1: Ia = 10.5 mA; gm = 1.9 mA/V

A21: Section 2: Ia = 10.5 mA; gm = 1.9 mA/V

 

A22: Section 1: Ia =10.0 mA; gm = 1.9 mA/V

A22: Section 2: Ia = 10.0 mA; gm = 2.0 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.
