Honestly, most radios are all made in Hop Sings factory in china. Standard maximum output is 25 watt on high, 1 or 5 watt on low. Most radios have the SO239 standard antenna connector, some used to have the BNC. As long as your power cables are clean and not corroded, they can be reused, any amount of corrosion, replace them. If your antenna is as old as the radio, it may be a good idea to change the antenna too.
