hmmm... it appears that I have more oscilloscopes than I remembered
475A - works, needs a complete refurb, hamfest find, first bench scope
465 - no display, probably PS caps, don't remember where it came from
466 - no display, probably PS caps, received from a neighbor
468 - left for dead in a trash bin, parts mule
531 - saved from being scraped, works, as old as I am, on the shelf
2215 - works, on the shelf
2216 - saved from trash bin, missing attenuator, parts mule
2465 - current bench scope, needs a complete going over
TDS420A - works, not sure what I am going to with it, on the shelf
And a DS1054, a birthday gift from my wife, also on my bench.
The first on the list is the 475A but I have to finish rehabbing the stack of TM500 plugins first. Got another one calibrated today then found that the offset pot was fubar.
So find a replacement and run through the calibration again.
