In spite of some delays and missing parts, the 89 is moving along rather well. Nine of the ten potted caps have been restuffed, I just finished the two 6uf electrolytic cans, fixed the volume control, replaced a couple resistors and found some perfect rubber grommets for the tuning cap. I'm waiting on some cloth wire, 680pf caps, and resistors.
Moving on to the broken oscillator coil. I was planning on cooking it in a toaster oven for a while, as per many online suggestions, but the form looks to be made of some sort of plastic. It is hard and semi see-through, I was expecting wax covered cardboard. Does it still need to be baked before rewinding? I'm not sure how plastic absorbs moisture.. The primary and secondary are fine, it's that hideous tickler winding. Here a picture:
