7L5/Repairs: Difference between revisions

The [[7L5]] is constructed of two main modules and the front panel assembly. The left module hinges outwards once a few screws are removed, and with further screw removal the complete front panel assembly comes off. When further disassembling the front panel note the unconventional "Frequency Span" and "Time/Div" switches that need to be removed to be able to lift off the front panel overlay. These are entirely build into the particular knobs and can be pulled off from the front panel as a complete unit after removing two fasteners at the back. Note that the "Time/Div" switch has very thin metal contact fingers that fit into a socket at the front panel PCB. To guide installation there is a little plastic spacer with conical holes for those pins. Make sure to install this spacer in the right orientation before attempting to reinstall the "Time/Div" switch, as shown in the figures.
