We guarantee and test all our vacuum tubes based on the manufacturers tube Manual specifications using
uTracer3+ curve tracer & Tube tester, regulated DC and AC power sources, benchtop and
handheld multimeters for accurate precise repeatable measurements.
I love my TV-7B, Hickok 800, 6000A, EICO 667, and my B&K 700. But these are just tube testers
and not true parametric testing equipment. They are for "Go - No Go" testing and are best for weeding out bad
and weak tubes.
Truthfully, the best way to know how a tube will work is to use it in the actual application. The
next best thing is to test it at the manufacturers parameters in the tube manual with proper lab or
bench testing. This way one knows how close the tube is to it's designed standards. This may seem
excessive, but we try to offer the tube amp builder, technician, and musician the best service and
product we can. More tubes to come.
