Since this will be the first ever tube tester I bought, any comments/input/do's and don'ts would be appreciated.
I have also read that calibration tubes are used to calibrate testers, are these a good idea to get?
Also, how can one tell that the tester is still in calibration.
Once I've had a chance to play with it, I'm sure I'll have more questions.
And yes, it comes with a full set of manuals and the dial is supposed to be in very good condition as well.
