Currently working on a Graph 303c oscilloscope (~1959) similar to shown in link below.


The 'scope has been sitting in the garage/attic unused and unloved since I acquired it sometime last century (mid 90's).

I've located a poor quality scan of the circuit diagram. But wondered if anyone has a scanned copy of the original manual & circuit diagram ?
