you should Discharge the HV from the CRT completely before testing on a CR-31, this would cause Erratic Testing, the pop you heard could have been a HV discharge to chassis Ground since its been modified for a newer tube, I went thru this on my ctc-4 before the CRT got rebuilt when hawkeye was in business, there is also some mods in the Gun Drive Circuit to make these newer tubes "run" correctly, color Temp is a bit different
Good Luck!
