I have a Old oscilloscope that has never really worked, its pretty crappy and i cant read the name on it. The bandwidth is low, I cant remember off hand but its around 2 or 10Mghz, I would like to fix it as I am building a component tester, so would be great to use that scope for it, that way I can leave it semi permanent connected.
The problems are probably many but its a basic machine and old, so shouldn't be too complicated, also its purely analogue, the main problem is the dot is a splodge! no definition to it, you can tweak all you like but it dosnt change, also when I put a signal in nothing happens, it does however sweep across the screen, so what section should I look at first? and is it likely I will have to mess with the tube and the very High voltage stuff?? (answer no to last question )
