Thank you very much Parasuraman for your detailed article on troubleshooting the the power supply of OSS Team T-12 soldering station. I had exactly the same problem with my Team T-12 X-Plus model and your detailed article was a huge help in making my soldering station functional again.
I am describing what I did and that may be of help to some. I ordered ES-55 Version 2.1 PWM module from easyspares.in (Rs 60 + shipping). Removed the damaged MOSFET 10N65C and the PWM IC 63N05P. Soldered MOSFET 11N80C and the module board the way you have done, connecting all 4 wires to the right spots. The 33uF 400V filter capacitors were not damaged but I replaced them with 33uF 450V caps for a higher safety margin. Since the 450V caps are slightly taller, they had to be fixed in the horizontal position. Replaced all four M7 diodes of the bridge rectifier.

Those style soldering stations are great tools to have, the KSGER is a close cousin to the X types, they all are 24 volt T-12 style irons.... The bad thing is the Earth ground is not connected to the aluminum cases because of the coating on the cases.... Buddy with The Radio Shop on you tube and John Salt have great video's explaining the issue and show how to remedy that issue...I don't have a soldering station like those but I am saving up for one ...
