Hello,
Foolishly, I was attempting to align this radio with a screwdriver and shorted something in the process. I was very close to finishing and now, there is no sound, the wirewound resistor(part96), transformer (part 92), and one of the 6A3s all get very warm almost hot to touch. When I power up the radio, I observe the B voltage at the input filter(part103) climb to about 280vdc then there is a pop in the speaker and the voltage drops in a hurry to about 150vdc and things start to get warm.The power transformer seems to be ok. Live and learn, as I should have known better. Where should I look to troubleshoot this problem, please point me in the right direction. Thanks, in advance.
