[R-390] 17 MHz Crystal

[Steve Hobensack]

Usually a bad crystal can be repaired. dismantle and remove the crystal. Soak everything is soap and water. I have found that degreaser spray does not work as good as soap and water. Use a toothbrush. rinse several times, final rinse use distilled water. Also check electrical continuity between the pins and contact plates. Dry the crystal with a clean cotton dish towel. Use a hair dryier on the holder. It works most of the time for me. It even improves chirpy/lazy crystals.
