In addition to the diode and the resistance, the mosfet in the same circuit was also defective. After replacing the defective components, the power supply still did not work. Unfortunately Jeallen turned out to be right, the winding of the transformer is broken. Repair is therefore no longer an option. I would have liked to use the SR8700 as a better positioner instead of my current V-box-II.

It may be possible to get a replacement transformer if anyone has the specs for one.

Happier news here. I replaced the two big caps in my LT8700 and it sprung to life.
