Howdy all,
Along with the below post/radio. I also received an SX-110. I got it to receive a station, but after the long trip back home from AL, I can't get the radio to receive anything. I re-seated all the tubes and did not see anything caps/resistors that were burnt. All the tube that are clear have a glow to them. The speaker does not have any static, well, occasionally there is a little, but not much. What to do? Where should I look first? Also, there looks to be some type of mod? There is a wire that comes out a hole under the speaker connection. It is like a common 2 wire houshold extension cord that connects to a wire that runs from the avc on switch to the receive/standby switch and the other wire goes to a cluster of resistors that is back and center of the radio. Any one? Thanks again for your earlier replies to my other questions! Thanks in advance! Jim |

Maybe take a look at "Troubleshooting a Superhet Receiver" URL:

About the worst thing you can do to an older RX that has not been plugged in for years, is to plug it in and turn it on without recapping the RX. It is possible that one of the caps shorted when you first plugged it in and taken out something important like a transformer or IF can. Dale W4OP |

You rarely can fix a boatanchor without at least a schematic to tell you
where you're going. Suggest you download a manual from BAMA http://bama.edebris.com/manuals/hallicra/sx110/ Then figure out that haywire modification, and go from there. --Chuck "Cowboy67" wrote in message ...

Hard to know for sure based on your description, but it's *possible* that this 2-wire pair went to an antenna transmit/receive relay. Those relays usually had an extra SPDT switch for muting the receiver during transmit. I used a similar arrangement on a couple of receivers. If you're feeling lucky, you might try shorting the two wires together. Art N2AH |

If so, you can almost certainly troubleshoot and fix your radio. Frank Dresser |
