I've always considered drugstore testers as a waste of space.... get a portable like the B&K 606 I use predominantly.... any tester at this point is equally at risk of inaccurate readings. Most "portable" service testers have published service and calibration online. You can run thru a cal and if it fails just change a handful of resistors and caps and next time it should pass.
Also some tubes like sweep and HV cannot be accurately tested on any tester because no tester was made to deliver the high current and or high voltage the tube gets subjected to in normal applications. I seen plenty of HV rects and other sweep tubes where readings in multiple testers don't match actuall in set performance.
Nice anime catgirl avatar ya got.
