Just when finishing up a project at a client the old Tek 2465 over there croaked. And I hate working with their digital scopes. Wanted to switch from delayed trigger to normal and it felt like a broken clutch. The plastic actuator fell into pieces. Upon disassembly some of the little knobs also fell apart, they had also become brittle.
Couldn't find any of this at Sphere's web site and others, only custom chips and stuff for these scopes. Is there a reliable place that has such knobs? These scopes are certainly out of support but so widespread that there should be a market. Thing is, the knobs have partially turned from gray to "nicotine brown" and hardened up. It's only a matter of time until the next ones crumble. So I guess "new old stock" wouldn't help much unless it was really newer than the scopes and stored in a cool place.
