i have a palomar 250,i was talking on it then i went in the house and i came back out and no power out put.but it would still key,so i ordered 2 new transisters and put them in and it still keys the relay but still no out put. i checked all solder joints there in good shape. what do you think is wrong? thanks |

Did you test the other two transistors with a DMM? |

i uesd a ohm meter and the new ones and the old ones show the same,i think there all good cause it does the same with the new ones it keys the relay but no out put on my meter there is 2 black diods 1 is for protection and what is the other for across the board.well i hope we can come up with a solution. thanks |

An Ohm meter will not work unless it has "diode check" built in , you need to bias the junctions to test them.. |

new jumper relay keys and what does the trimmer look like,and i figured out that my antenna was messed up when it quit. i fixed bad conection now 1.0 swr. but even after puting new transisters in it it will key no out put. somone told me there are diodes that are in the out put side that might be bad.sounds like to me that its somthing in the out put circut.i am pretty fair with radios but i never messed with a solid state amp till now |
