Search on eBay for a PLCC chip extractor. You can find them for less than $5 from China or a bit over $5 from the US. I'd post a link but I don't believe that's allowed.
Once you have the extractor in hand, *carefully* remove the chips on the RailSounds audio board, letting the extractor do most of the work. Give the contacts a quick spritz of your tuner cleaner, and reinstall, taking care to make sure the chips are in the same orientation that they were in originally.
