Construction video of my new uTracer V6.
Previously, I built uTracer V3+ which also very good Tube Tracer/Tester. Only somehow voltage and current is a bit limited.
You can see the comparison below.
uTracer V6 could support up to 1000V and 1A of current. Grid voltage also enhanced up to -100V (nice for 300B for example).
Hope you enjoy the video below.
