If the ohmmeter shows a dead short, then you probably cooked the final transistors. Hopefully, you did not cook the VHF or UHF transmitter as the transistors are no longer available. Yaesu had to discontinue manufacture of the FT-847 due to loss of supply for these transmitting transistors.

this is "interesting", I was just looking for an used FT-847 for my shack. No equivalent parts from other manufacturers also? If I get one I will surely add a sacrifical diode across the power supply, but first I'll start digging informations about the unobtainable final transistors.
