Id be looking at the audio section. Get a service manual if you can and look at voltages around the place. |

The first thing I would check is the voltage regulator and/or bridge rectifier in the power supply.
Try this.... If you have a volt-ohm meter, ground the negative lead and put the possitive lead on the power wire that goes to the main board from the power supply. See what voltage is there. It should be around 12-14 volts. Then key the radio and check it again. If the voltage drops substantially, then it's definatly the power supply.
The way you explained it, sounds to me like a possible power supply problem. But, I could be wrong. There are other possiblities also.
Good luck and 73s.
