[Kenwood] TS940 catastrophic failure

A TS940, another one, has recently arrived in my shack in a rather sick 
state. The radio was imported here from Japan and has the Japanese 100 
volt AC only transformer. The owner has been using it on a 115 volt AC 
transformer to drop the voltage from our 220 volts.

As received the radio is completely dead. One of the two large pass 
transistors has a collector to base short. And I suspect significant 
other damage.

I suspect the cause is the use of 115 volt AC to powrr the radio with 
instead of the specified 100 volts AC. Would be interested to know what 
other likely damage is before I decide to progress it further or suggest 
the owner invest in something else.

Thanks
