I noticed the mechanical push button tuning is sluggish and does not work well, although the tuning knob does seem to work. I do not see any convenient way to disassemble enough to get a good look at the push button inner workings. Do you think WD-40 is good to try for those mechanical parts of the tuner?
Just looking at the closeup pic of the switch, there's plenty of openings for the DeoxIT to get in.. Place some paper towels on the table/bench and place the radio on them.. Have a spraying good time, the paper towels will soak up the access.. I don't like using WD-40 on electronics.. It's intended not so much for lubrication as an agent to absorb moisture, doesn't leave much residue behind.. You need to use something that will leave behind some "slickness".. DeoxIT should also work for that...
