Yep, did that once, but can't recall why, as Motorola and Zenith had instrument repair/calibration departments that normally were the only ones to access the insides.
There should be a small spool of silver solder bolted to the chassis somewhere if no one has stolen it.
A lot of our scopes had a burn spot at the lower left corner of the graticule from using them to do X-Y plots of device safe area (I vs. V) and forgetting to turn down the beam.
