The uTracer Tube Tester and Curve Tracer
I have completed building my uTracer (micro Tracer) computer based vacuum tube tester and curve tracer. This unit, designed by Ronald Dekker described on his website:
The uTracer is much more than a simple tube tester; it is also a curve-tracer. It measures both the anode as well as the screen currents for a range of specified bias conditions, and arranges the measurements in meaningful sets of curves. From these curves parameters like the transconductance or the output resistance can then be extracted and plotted as a function of bias. Alternatively the uTracer can be used as a tester which extracts important parameters like Ia, Rp, gm and um in your favorite bias point in a matter of seconds. http://dos4ever.com/uTracer3/uTracer3_pag0.html
Ronald Dekker makes this tester available as a kit, with detailed assembly and testing instructions. One of … Read More »
