    That really was an easy fix. The scope came from the UK Ministry of Defence, who probably had it on a shelf for 20 years before auctioning off, hence the lack dust. When I brought that scope, I brought several others of a similar vintage that were in equally good condition.

      Cheers for the info Aaron. Yes, it has a sticker on the side which I looked up........"Welbeck Defence Sixth Form College" of which was institution of the Ministry of Defence (MoD). Closed in 2021.

    I have the BK version and I love using it since it also has the built in component tester.

    The front panel design and even moulding of the handle are very Tektronix-like, haha! Nice beginner scope, plenty of life in it I'm sure.

    Nice to have a simple repair on such a complicated piece of equipment. Thanks for sharing.

    An easy one! OK, who else saw right away the classic pattern of AC Humm when Ian first tried the digital store? 👍

      Next time, I'll disguise the bulging cap with maybe the part number of an inductor or resistor......maybe we'll get a different response...:-)

    11:50 the scope triggered on the junk signal when you plugged in your signal. "Reset" just resets the trigger, waiting for another one. You should have more subscribers, all your videos are so well done!

      The number of views per video are high, much higher than the average Subs/Avg. Views Per Vid........but yes, it would be great to get the subs up. Thanks for the comments.

    Had a Tek 2232, and yes the digital board decided to die, dead capacitor, a shorted Tek favourite, tantalum bead across the 5V rail. As I needed the scope that day, just unplugged the digital board, losing the ability to store, and the nice readouts, but the analogue side was still perfectly functional, so I finished the job, then sent it in for repair.

      I think the devil is in the detail, Digital "Storage" oscilloscope, so all it does is store data in ram and replay it. There's no uP.

    Only simple problem worth the effort to repair these scopes. A new one is only US $200!

    For a "cheap" scope, it is remarkably well made. Would have been a shame to scrap it, but the question is will anyone now use it??
