No, I meant exactly what I said. When you are removing epoxy potting compound, put it in an oven set to 140C, and let it cook until up to temperature. The potting epoxy will become about as soft as pencil eraser rubber. You can then pick at it, and get pretty big chunks to come off. When the epoxy starts to feel hard again, pop it back in the oven.

This seems a bit toasty and is equivalent to 284F. Maybe meant 140F not C?An oven set to 140C is your friend when doing jobs like this.FWIW, the GE Progress Line two-way radios oscillator crystal holders had an octal base, held two crystals, and the heating element could be used on 6 volts or 12 volts depending on which way the holder was plugged in. I have no idea of how well they held the temperature. Always planned to use one with an external proportional controller but never got around to it.
