Greetings everyone,
I bought the old 'scope in from the shed and it has been next to a radiator for a couple of weeks to dry out nicely. Yesterday I turned it on to see what it did, well one capacitor was getting warm and leaking wax, and another was dead short after a while.
Thankfully, the tube is ok and most functions seem to work although the pots are a bit noisy. Here is old and new working together with the 'scope showing a clock display generated with an ESP32 as an NTP time receiver.
There is a problem withthe frequency response which is causing the distortion in the number display, I'll investigate the and see if it can be improved. A more modern 'scope without very high frequency response shows a much better clock display.
