The history
I acquired this oscilloscope at the Hunstville, AL hamfest for $40. The seller assured my that it worked the day before, but I didn't believe him because if it was operational, it would have been much more expensive of a scope than $40. I gave it some thought and thirty minutes later, I decided $40 was an acceptable price for a dead boat anchor. If it actually worked, well, that would be a nice bonus.The scope was dead on arrival, so I stored it away. I powered it up and inspected it internally and discovered multiple power supply outputs were not operational. I did not document the specific missing voltages.
As I needed to fly to Europe for an extended stay, I shelved the project for 6 months.
The Goal
To have an operational oscilloscope by remaining faithful to the design.
I intend to:
- Replace consumable or high risk components with modern equivalents that meet or exceed the original specifications.
- Maintain as much of the original design as possible.
- Perform a calibration to ensure the oscilloscope is able to perform within it's original standards.
