I’ve spent a good amount of hours reviving a broken SRS DG535 pulse delay generator: https://www.eevblog.com/forum/repair/srs-stanford-research-d...

There were many detours and scenic routes taken for what turned out to be a pretty straightforward repair in the end, but that’s not uncommon for these kind of things.

I’m on my way back from Home Depot to buy some screws that were missing (and a Xmas tree.) Soon all that’s left will be writing a blog post.
