[ICOM] IC-471A

[GGLL]

GM, it seems a hard to find manual (service). The symptoms you described
maybe related to PLL. Check trimmers and solder joints. Also for dirty
board connectors.

Besides these:

Trimmer Replacement and Adj.

Schematic

You may try mods.dk also, but it does not have the service manual, just
schematics for E and H versions.
