Radio Shack used to have a small transformer that would run the new 12 volt relay you would have to install in this example. I think it is easier to use the keying circuit in this example to key a small 12 volt relay. That would then key the stock 120V relay in the Heathkit. If you need more info I have it somewhere in my files and can dig it out for you. |

Cellphone Shack USED to carry a lot of parts. You go in the store and ask for electronics parts and the associate will stand there with a dumb look on his/her face and say I don't think we carry those parts. But please come over here and let me tell you about the specials we have on the latest cameraphone for a small investment of $200.00 and a $500.00 deposit we can set you up with a great monthly plan that will take the place of your radio stuff. Ya wana bet that's not going to happen. Sorry Bruce, I just had to use parts of an old post of your's. |

Take it off standby and key your microphone. If it don't key, it needs repair. |

rawhide, what is the keying tube, a 5AQ5? u know this amp requires about 90-100w to work, and prefers about 130w. also, it is best to run on 220vac. does it have the 10 meter mod also. hope this helps. |
