Ref: The 3900, don't overlook the possibility that it's just a physically intermittent carrier balance preset, if there is a preset (I'm not so familiar with those ones).

For the removal of surface mount caps you really need TWO soldering irons with fine needlepoint tips. Put a bit of lead-tin solder on the projecting end of each 'foot' of the cap and then heat both sides at once and just use the two irons to 'tweezer' the part off the PCB while the solder is melted on both sides.
