This video details the repair of my IC-706MKIIG. A final transistor failed in the unit, causing the radio to draw 10 Amps of current even when the power is off.
Older versions of the IC-706MKIIG (Like mine) used SRF-J7044 Mosfet transistors for the HF finals. Those transistors are now discontinued and are no longer available. I replaced them with RD70HHF1 transistors that Icom now uses. Unfortunately, they are not the same size, and circuit board modification was required.
