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.
