The uTracer comes as an easy to assemble kit.

SMDs already soldered, difficult components in labeled bags
and including an extensive step-by-step printed construction manual.
Have a look at the construction manuals: uTracer3+ or uTracer6

Look how others used the uTracer to realize their dream tube tracer / tester!

For many more examples have a look at here: uTracer3+ or uTracer6
