Try some canned air on the final to cool it down .If the radio comes on then you have the problem child.

For most CB radios, some common components that fail and would cause a fuse to blow would be:
1. reverse protection diode located right after the power connector at the very rear of the board;
2. finals (2SC1306/7 or 2SC1969);
3. filter capacitor, 2200uF/16V;
4. audio amp IC located on the side of the chassis; and/or
5. 3 terminal voltage regulator (780X) or a zener diode.
Alternately, a wire (after the switch) might have been grounded.
Hope this be of some help/idea. Post back how things turned up or should you need further information.
Good luck and kind regards.

The problem is most likely the audio ic . open the radio and see if the diode 44 is blown or see if you see anything that looks like it got hot around the plug area. if not contact me and i will buy it. is it an old or new 148 gtl.Read more

the dx 2527 has a fine ransmitter. it is choked out by the factory to pass FCC reg's. With about $4.00 in parts from the rat shack you can really make it talk. my personal 2527 dead keys around 3 watts with around 45 50 watts on rms with bird meter around 60 with crappy dosey.
