Hello all.I have a radio problem that's driving me crazy.The radio is an old royce am/ssb model 1-632.When I got it,I found the 2sc1945 final transistor to be bad.So I replaced the transistor and still no transmit.When I switched from AM to usb the transistor started smoking.The radio has push button mode selectors,when you select another mode the previous button pops out.I later discovered that the problem occured whenever the AM button was in the "out" position.I can't figure out what would possibly cause this.If anyone has ever had a problem like this or has an idea of what could cause this,I would be very greatfull for the help.Thank's and 73's..Alex.
