are you using the universal tester, its a bit tricky about setting the controls. the clips go to the correct pins (the clip on leads tell you which pin, ex. filament, K, G1, G2. After attaching to the correct pin (per the book settings) you then set the rotary switches 1,2,3,4,5,6. the switch settings do not correlate to the pins number of the CRT. It explains it in the book (how to use the unversal adapter which is really just loose pin connectors).
