wise -
I feel bad, wish I hadn't pointed it out. In hindsight, I guess it makes sense that if the RCA tube was obviously used, and the box was a Raytheon, somebody probably pulled the RCA, installed the Raytheon, and put the dud RCA back in the box. Probably a bad combination, to avoid in the future. Mismatched boxes, that is.
Maybe adding insult to injury, but here:

This guy's other auctions are electronics gear too, looks like he probably can handle a voltmeter. Maybe email first and ask him to ohm the filament. Screen doesn't look like it's lost vacuum. If you get if for 40 bucks, and it works nice, it might take the sting out of the other one.
But yeah, I'd be leery too. Once-bitten and all that. Sorry for the bum steer...
