Forgot to mention - Steve, you bring up a very good point. If you prefer to keep your 89 or 19 original, baking your set's oscillator coil in an oven at 175 to 200 degrees, for 30 minutes, is a must to drive out any residual moisture. Sealing the coil with lacquer after rewinding the tickler winding is also a must. And keep in mind you may have to drop that oscillator cathode resistor to 8.2K from the original 15K.

You should also bake the form before rewinding if you do perform this mod to your 89 or 19; and seal the coil with lacquer after rewinding.
