Welcome to Joe from the sunny south.
One thing that most valve testers can't do is sustained high power operation. Many will suffer burnouts, the Dos4ever design uses pulsed testing.
On the odd occasions I've wanted to test a valve I've used assorted bench power supplies and DMMs. Messy but effective. Slow if you want to plot characteristics but pretty much guaranteed accurate.
