Fluke 1503 Insulation Tester replacement Transformer T1

[klim]

Hi, I want to bring back by Fluke 1503 to life. The original Transformer had a shortage in winding, so i desoldered it from pcb. Now I'm looking for a replacement Transformer.
Too bad there are no technical details availible. The PCB device id is: T1. Below some pictures. I hope to get some help, many thanks in advance.

Thnk you for the pictures.

Are you sure the "short" you observe is a fault? It could be just a common ground.

Other Fluke meters have a low voltage transformer here to generate all the needed voltages but all referenced to the ground.
