    I have recently purchased a Gould 450 Oscilloscope, however, I have recently found several problems with it:
    - Firstly, the oscilloscope is unable to display any wave form between the 50ms and 2ms timebase settings. And if a calibration is performed when set to this the Oscilloscope freezes up and requires restarting.
    - Also, the full calibration hangs when reaching the 50ms stage and requires re-starting similar to above.

    Just wondering whether anyone has any thoughts to the problem and a solution (if possible) or whether a service manual is available.

    Many Thanks.
