I do already have an isolation transformer. I got that before aligning my 49-906 since it’s an AC/DC set. I didn’t dare to connect an oscilloscope or function generator to it without isolation!

Good call on the rivets and chassis connections. I do have a riveter hand tool, so I’m able to replace any which are corroded. There’s a couple as well which look to be mashed up. I’ll probably drill those out and put some fresh rivets in place. I’ve recently learned about naval jelly, so maybe I will give that a whack when I clean the chassis up. It’s got some rusted areas.
