[Texasrocker]

All you need is a good ol Wagner Heat Gun set on high setting, and some patience in melting tar in the old metal type cap cans, no matter wheather you own the kitchen or not. Just tryin to help. Just don't ever try what you did removing the tar in the Philco caps can trying to do the same in a old Atwater Kent Radio, you will chissel out the good original filter choke also. Just as long as you know what components you are chisseling out, you are A.O.K.! Not all sets are the same. That is where schematics come in handy, and I am glad your sets filter choke wasn't buried in the tar also. Using slow heat to melt these type situations instead of getting in a hurry and chisseling away, saves many good original components that are sometimes buried in the tar also. Live and Learn....Best of luck with your future vintage Radio restorations!
