[Central-Electronics] 10A crystal location

Temperature compensation is not difficult.  As I recall, the original circuit did not have any capacitance, so may be harder to stabilize.  I use my wife's hair dryer and a frequency counter and can quickly stabilize most circuits.  Hallicrafters had a wonderful circuit using a differential capacitor, allowing you to dial in the compensation required.
