My test equipment collection has grown yet again - I snagged a Tek 515A scope, and an ancient Triplett Model 1210 Tube Tester (more because it looks like it will be kinda cool cleaned up rather than for any practical purpose; it's from about 1936 or so).
Scope:

It has in interesting serial number (apologies for the blurry iPhone pics; I was too lazy to set up the good camera):

Unfortunately for the scope, some miserable prick bastard opened it up and pilfered all of the dual triodes out of it,

so I'll need to come up with (9) 6DJ8s, a few 12AT/U7s and various others before I can test it. I suppose I should be grateful that they didn't strip it bare, but it still peeves me as any calibration it may have had went away with those tubes. I hope their speakers blow!
There are a few more photos of the scope showing the dust & empty tube sockets along with a quick overview video at

The enclosure will need to be re-covered to make it presentable as a good bit of its outer skin is missing or peeling up.
