Almost finished: When I got the oscilloscope it didn't have the HV power supply cover as someone was obviously trying to troubleshoot it. I used the cover of an old ATX power supply. It fits very nicely. This is what the step response looks like. I am feeding a fast risetime square wave from a Tek 106 generator (<1ns risetime) into the scope input terminated to 50 ohms at 50ns/div. There is a lot of overshoot. This can be compensated out by adjusting the HF response of the vertical output amplifier. Vertical amplifier compensated. The step looks much cleaner now. And the end result is another nice oscilloscope from the 70's |

This is really impressive! What are you using to clean the front panels? I have a Philips scope from this period that is more-or-less functional but is a bit grimy. |
