I just put my HS in my friend's house and after 2min of play the displays goes out.
The fuse blow every time 0.25A
After that now PSU HV section is totaly damage but the machine play fine.
I will repair the board,no problem.
The problem is that his input volaltage is 250V instead 220V(Europe).I learned that when thirt fuse blew and decided to measure the input voltage.

I need to buy voltaga stability device.
He have and one arcade machine with 25" CRT monitor Hantarex.

My questions are:
1.How much power consumate the pinball at max?Wats and Ampers
2.Same for tha arcade?

I choose AVR(automatic voltage regulator) input 140v-250v output 220v 1500VA which is 900W.
What do you think?

Thank you for correction.
The machine worked fine 5 years without problem.
Now I will rebuild the whole HV section,put the AVR and will see.
Betwen when I measured the voltage from the transformer it's 55V.The manual said it must be 90V.I measured directly on the connector from the transformer with everything disconnected.Any ideal?Can be the transformer dead?I have one more from another High Speed so I can test with it too.

I will make stable power input first,after that will test the transofrmer's voltages and if they are not good,will replace it.
