The fuse is fine. There's a faint "burnt" odor inside the controller.
Transformer secondary voltages look good.
1. Does anyone have a legible copy of the schematic? Yaesu's PDF
version is illegible at the component level.
2. The interconnect diagram clearly shows Q1/D2 connecting to the PSU
PCB via J1007. Can someone please point out where the Q1/D2 circuit
is shown on the schematic diagram?
Thanks & 73,
