I received a this radio recently and ran it hot in a box with no muffin fans on the heat sink. intellegent. the radio turns on and is able to receive still. the needle moves in receive mode but not in transmit. did i burn out the duel 2sc2290's or could it be something like a drive or worse??????

It is lkikely that you burn the output transistors. You can easily check these transistors even if it is soldered but be aware of low resistance paths like coil , toroid, and lo ohm resistor which might affect the reading in the multitester. To be sure desolder at least 2 pins before testing. I do not think that the driver is damaged.
