The uTracer V3.10 – a curve tracer for valves Vol 8
Every serious tube buff should have access to at least one tube curve tracer. Some opt for a vintage, refurbished unit, some try their hand at one of the modern, PC-driven implementations. Morgan Jones, who by his own account owns more curve traces than oscilloscopes, puts the PC-driven uTracer V3.10 through its paces and reports with many sample graphs and usability findings. In the end, he very much likes the unit.
