Movement of L7 was transmitted to the circuit board trace through the left lead, causingthe trace to flex and break. In stock form, L7 was held in position via one heavy lead on the left side of L7, and the other heavy lead which can be seen soldered to the lead from T2. This picture was takenprior to the RTV application. I then tinned the newly bared copper trace area. You can clearly see that the trace is broken from the movement of L7. The blue-shaded rectangle at L7 represents the approximate size of L7, while the smaller inner rectangle is the footprint where L7 contacts the circuit board, and I covered that portion of L7 with RTV compound. Icom IC 781 Memory Battery ReplacementД¬omponents C4, L11, R35, C28 are most prone to heat damage according to Icom, and should be replaced. The broken trace is on the other side of the board where indicated. It is on the underside of the board, about1' long. Notecarefully which module uses the spacer, since there are three other regulators that do not use one. It's directly next to the final amplifier PA unit.

The service manual is a must for such a project, and I had no luck finding an original for sale. Since the nearest service site was miles away, I decided to tackle the job myself.
