    Howdy all oldtimers!!
    I have a model Dumont 2100 Oscilloscope where one of the traces is "off screen" and the vertical balance control will not bring it back up. This ia a vintage 'scope that works to 10 Mhz which serves most of my needs. I am looking for a schematic or the service manual in PDF format.
    There is one of these 'scopes for sale on eBay. Seller is # 114586205170 and you can find a great
    picture of the controls. I have searched many sites and have come up empty. Any suggestions are greatly appreciated.
    73s, Doug

    Hi Doug. May I suggest that you clean all switches and controls with contact cleaner before doing anything. Not just the ones on the front panel but any internal trimmer pots too. Use a pencil to mark their position, spray and turn them back and forth a few times.
