Tube Tester -Need Help!

Hey Cats-

My buddy just got and is re-calibrating a nice 1967 Tube Tester.
We have working tubes and plenty of capacitors, but no old DEAD tubes! I need a couple of various sizes that match this tester for control tubes.

Any suggestions for a good recource?

Thanks!

..mount a resistor in series with anode or cathode - or lower heater voltage - to emulate bad emission..
