Search the same auction site you bought the radio from for 3mm male banana plugs. The 3mm banana plugs are not technically classical wander plugs but should fit in the same socket. Finding the 3mm ones can be a struggle, and there is much more choice on AliExpress if you feel comfortable ordering directly from China. Some require soldering and some have got a screw for a solder-less connection. Good luck. (Note: one of my radios needed a 4mm banana, so sometimes best to order both the 3mm and the 4mm pin size.)
