My Oscilloscope arrived today. The same exact model I had 15 years ago. Though one or two of the interchangeable modules were different. This one is dual beam, with 2 differential amplifiers and one Time Base amplifier.It's in good cosmetic condition, after a good cleaning. I believe this is a Goodwill or Salvation Army charity/thrift store discard. I worked at a Goodwill store with donation drop-off center while I was attending tech school in the early 2000's and they would not sell any electronic donations, beyond TV's because the the Goodwill regional President had heard that electronics contain PCB's and she knew PCB's were toxic! LOL! And this Oscilloscope has it's power cable cut off as they had us do to all electronics before tossing them. I explained the situation to my manager and a regional guy when he dropped by once, to try and stem the tide of vintage electronics going to the landfill for no good reason, but I was a nobody, so... There were also some loose wires hanging out the top when it arrived, so I removed the side cover to investigate and there is one board missing from it's spot on that side. It looks like someone was bypassing a bad board that was removed with something external as the loose wires were connected to a wire harness from the PSU board. I'll have to investigate. In the meantime I'll repair the power cord and power her on and see what works and what doesn't. Here it is on my workbench, amidst a Sophia 2 and PBI cable install. My little workbench is getting crowded!
