Hi TekFan, Thanks for the quick response. I thought it will not be too easy… In storage mode I get a good picture in only one position: PERSISTANCE min., BRIGHTNESS min. The storage controls (PERSISTENCE and BRIGHTNESS) do absolutely no effect in CONV mode. That’s ok. |

I show the rest: |

I have a dead storage scope mainframe somewhere....... Think the tube still works. |

Does this phenomenon show an obviously defective tube? I would trust in the TekFan’s experience firstly… Tube replacement would be? Then the spot remains… Despite the spot it could be used in conventional mode. |
