Re: Tek 7603 missing readout but present when beam finder pressed

With readout control fully clockwise I suspect the readout is actually offset vertically because there is a faint brightness at very top of the crt (just out of the visible area). If you reduce readout brightness it disappears . When the beam finder button is pressed you get a compressed display of the traces and the readout as expected. The readout line text appears to change when tge input ranges are changed via the front panels. So Im guessing the vertical output from the readout board may be the issue here.
