The little hole in the PCB in the middle of that exposed copper area (seen in the photo), leads directly into the adjustable 7.8uH coil. I was able to get close in value with a fixed value coil, and the oscillator covers about the same range it did before the damage. At first I feared that the band switch was contaminated, but it was fine. The frequency range is controlled by a string of adjustable coils, all in series. The band switch shunts around them, so for lower frequencies, more coils are in the path and increases the inductance of the string. That one coil was open, so it wouldn't oscillate in the two bands controlled by it and the next series coil to the right. I was lucky that was all the issue was.
The schematic seen in the following pictures is also on my website at http://www.WB4IUY.net , mouse over [WORKSHOP] in the menu at the top of the page, then click on [SCHEMATICS MANUALs] in the drop down that appears.
