A friend of mine has an old iCom HF radio of his father's. He noticed when he opened the radio up that his father, who was a long-time Ham and electronics' tinkerer, that it had this component soldered to the lead of the SO-239 connector (he removed if from the radio). I have never seen a component like this before but think it is resistor but, honestly, I am not sure, just guessing. No, I do not know what the other end was soldered to as I haven't looked at the radio myself and the guy really didn't know either, he really isn't good with radios or electronics so... Does anyone know what this is? Any guess why it is soldered to the pin of the SO-239? Also, the component on the left, is that an old-style lamp used in electronic gear to light up meters or...???
The item on the left, is a Gas Discharge Device, and depending on the Gas, (Neon) could be a Neon Bulb…The item on the right is an enclosed Terminating Metal Film Resistor…
yep yep can be found on ebay [ Taiwan ] n aliexpress [ chin ] part num DSA-### DSA-###xx 1x DSA-301LA 300V 2kA Through Hole Surge Absorber , Gas Discharger Mitsubishi | eBay
Big thanks to all! Thank you! So, we got an old-style neon bulb and a gas discharger for protection... Function of gas discharge tube: Gas discharge tubes are extensively used for the protection of telecommunications plant and equipment against overvoltage caused by lightning, power switching and fault conditions.
