Re: 7704A - Delayed Sweep Intensity Too Bright



Maybe the discussion of Aux Z axis Control and Aux Z Axis Out on pages 3-16 and 3-17 of the 7B53A manual will give a clue. It describes the Z-Axis interface to the mainframe. Since the 7B92A has a front panel contrast adjustment, the interface probably has the ability to control intensity via a voltage level. Perhaps a bad component in those sections of your 7B53A has that level pegged.
