- 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.
Here is the video of the process.

Thank you a thousand times for the nice details that EB5AGV provided in doing this mod.
