Ideally (and I mean - ideally) a scope would be sufficient, better - with audio oscillator. This makes it a 20 minute troubleshooting (including setup time).
And a transistor checker - but this is not really needed, in a circuit like this one simple making sure your transistor works is enough so an analog multimeter will do. Also a non-working transistor with a scope and oscillator is so obvious you simply yank it and replace it without checking much.
