Old radio - is this line-powered?

Fix it up into a ghostbox

I had to look that up. Wow, you're right, people who believe in that sort of thing are really crazy!

Don't know if any of these relate to yours or if they are even the same Viking, but Sams has a bunch

Some Vikings here:

Also AES has old radio schematics, but I see no Vikings. But a call to them might net you information on where to look.

You could also ask the seller for more information, additional detailed photos etc.
Doesn't hurt to ask.

Beware. If the seller tried to hack it, then it obviously means he tried to power it up. Depending on what he actually did to it, he may not have replaced the old paper/wax insulation DC blocking capacitors. They are very frequently leaky (Frequently as in 'almost always, you can bet on it.'). This may mean at least the 6V6 output tube may have been run with B+ on the grid through a high value resistor, essentially zero grid bias, so it may be dead.

If the 6V6 died a violent death, then it may have taken one or both of the transformers down with it.

I have plenty of experience with old tube based radios. When people have hacked into a radio like this, wires dangling everywhere, then I would expect that *none* of the components still works, and be positively surprised if they do. Maybe none of the circuitry under the chassis is still there...

Thanks for the warning. You've certainly given me something to think about!

(Cute username, by the way!)

+1 on leaky paper caps. Most of the old radios I used to work on pretty much needed every one replacing. With this kind of thing I like to pay just enough so that in the worst case I'll always get something out of it of value. A bit like an electronics-store goody bag.
