Hi

You wrote that there is no ~30 Volt at the 4000uF Cap?

If you try to check the fuses,

!!! VERY FIRST PULL THE MAINS JACK !!! there is live voltage connected to the fuses!

I would check the fuses first, there are 2 of them in the black housing in front of the Transformator.

If they are measuring good close the black fuse housing and plug the mains back in.

Next I would  check AC Voltage at P3 PIN 3 and 4.

After that check DC Voltage at P3 PIN 1 and 2 (4000 uF Cap)

Show us the results.

After that we look further.

Kind regards

Christian
