My old oscilloscope finally died mid-diagnosis last month

I was working on a vintage stereo receiver at my bench in Cleveland. About 30 minutes into tracing a noisy channel, my trusty Tektronix 465 just went dark. No pop, no smell, just a dead screen. I spent the next hour digging through my parts bins and found a bad capacitor on the power supply board inside the scope. Replaced it with a spare I had from a kit, and the scope fired right back up. Has anyone else had a piece of test gear save itself by being repairable like that?

Get any idea what batch year the bad cap was from?

My Tektronix 475 did the exact same thing two years ago, fixed it with a $3 cap too.
