These have the cardboard outer layer but also have a cardboard at each end with a hole that the lead comes out of. The end of the outer cardboard tube is then rolled down to hold the ends in place. I thought about trying to unroll the end but felt I'd tear it up too much so i sliced off the rolled section, then with heat gun I was able to get the cardboard end off and slide the guts of the cap out. A little cleanup with mineral spirits and I have a clean tube with two nice end sections to stuff the new cap into. Finally a little hot glue to put the sliced off section back in place and we're in business.
Pics show the as-received view (lots of mid-air component connections in this model which I believe to be original...much different than the Philcos I've worked on), sliced off section with original end still in cap, and the recap partially reinstalled. The last pic is my first attempt to make one of the molded resistors that needs replacement; I need more practice!
