Ron;
  I will have to keep my eyes open for those newer fused plugs, they used to sell aftermarket ones like that for use on TV sets. Though I personally don't think it's necessary in most instances, they are a much more elegant alternative to the hacked in fuse holders I see some people adding to vintage sets, especially the 12 volt plastic automotive ones that are not even rated for 120 volt use. As for the tube shield bases someone could make a cottage industry of making reproductions of the 1937 style ones, given how many of the 1938 and later ones seem to get hacked. Those later ones are a stupid, and might I say, vindictive design, they rub me the wrong way much as the silly security screws that seem to infest modern appliances, if I own it it's none of their business to keep me from opening it up, just as it was none of Philco's business whether someone wanted to use metal tubes in one of their sets.
Regards
Arran
