I've seen a few Philco schematics that indicated shields on tubes (by a dotted line surrounding the tube on the schematic), but most do not. The 38-7 schematic does not show shields on it. The only way to tell is to look on the chassis - assuming that the original shield bottoms surrounding the tube sockets have not been removed, that is.

I see the shields on eBay frequently; Play Things Of Past is another possible source.
