No way really, I've found that you can fog the glass like a mirror and often times it will be readable. I highly doubt that Normende radio will use any American tubes. The Germans made things a little "different" shall we say. Nice radiof, but a different beast from the American stuff.

I was looking into build an amp a few years ago and then got my 911 instead... So project time and skill set has kind of stalled any amp building.

You can find tube data sheets easily online. To get a ROM value for them, Tubesandmore.com is a website that has a pretty good selection of tubes available. They are a little proud of their stuff, but at least you'll know if you have anything that's substantially valuable.
