IMHO, I would stick with the grommet and underwriter's knot w/ some RTV. If memory serves, the correct hole for a Heyco Clamp is shaped kinda like the mask for a "roundie" pix tube, to prevent the clamp from rotating. I can't remember if you need the Heyco pliers to insert the clamp but they are handy for removal. I actually got lucky getting the molded-on strain relief off a power cord once (Both the cord and the strain relief were rubber and, somehow, the rubber was in good shape.) I can't remember if it slid off or if I cut the wire and then drilled out the rubber, but I slid brown 18 ga wire into it and cemented it with rubber cement. It looked like the original. Think it was on an early post-war Philco AA5. I have a 48-206 that was totally unmolested, complete with back, rubber power cord and plug in perfect condition and UL sticker. Even the grille was in good shape (Styrene vs Tenite?) I bought it because a friend was restoring the cabinet for a 42PT94 that was his dad's. I had restored the chassis (rubber all over, of course). The tenite grille was a disaster, but he took the white grille from mine and used it to mold a new brown grille (complete with streaks) for his.

The 48-206 was in such good shape that I should have stuffed the caps, but just replaced them instead. I have not tried to salvage the wax exterior of paper caps. I have done the mid-late 30s vintage RCA caps which are like firecrackers, that were in my RCA 5BT and 6BT Farm Sets
