content: Hello, I recently tried to repair a Keithley 2001. It had the issue with the leaked caps. I replaced all of them and many ICs because of heavy corrosion on the traces and footprints. I rewired all of this. On first startup, I recognized that the transformer has a short on the secondary. Due to this, I will sell the unit completely or the parts. The digital section is completely fine. Please contact me if you are interested or have a replacement transformer.Thanks

content: With enough effort it is possible to rewind the transformers. Considering how expensive the multimeter is, might be worth a shot.

content: The Transformer is completly shorted beetween nearly all windings. Even the two secondary windings for analog and digital are shortet. I think this happens because of an short circuit on the analog board due to the Leacked caps. Then the transforemer got really hot and the internal windings melted together.Yes you can easily rewind this sure. Because out of this reason I want to give away and dont throw it in the bin.

content: Yes, thats right. But not below 1 Ohm on secondary and drawing over 100W on the primary by 230V with nothing connected.

content: What is still available?I might be willing to try rewinding the transformer, but I'm probably going to get destroyed by overseas shipping.
