I just added a jumper around (well, actually over) my L4. No need to risk
possible PCB damage by completely removing the RFCs.
Unless the RFC begins to move under heat and begins bridging to an adjacent
pad or trace. Even when being careful, SMT/SMD parts can slightly shift on
the PCB.
Just my $0.02, but I prefer the removal of the RFC and short the pads with
0-ohm resistors, or fine magnet/buss wire. Removal of surface-mounted
components is generally easier than that of through-hole components. Also
important is that owing to packaging density, some of the pads and traces in
the K3 are extremely delicate and it does not take much lateral pressure on
some SMT/SMD components to accidentally remove a pad or trace. No matter
what style of component work-around you use, treat the pads and traces with
utmost respect..
Also, as Lyle pointed out, L4 and L7 in question are on separate PCBs (Main
DSP Board and KIO3). Anyone contemplating the mod should first familiarize
themselves with the schematics or they may be removing the wrong component
since identical component designators are used in the K3 across multiple
PCBs.
