Sure VHF Wireless Microphone SH-200 transformer replacement

Hi everyone.
I have the following device: Sure VHF Wireless Microphone SH-200. The problem is a broken transformer of the transmitter. I attached photos. It has some marking (KU3). What is the type of the transformer. It would be great if I can find it on the local Ukrainian market… However if somebody knows where I can buy the replacement please state. Thanks.
