You should have 10 volts at least and the real value is only 5,4 volts

Do you have 2,2 ohm at R1-R10?

Can you please check:

AC voltage between X1, 1 and X1,2?
DC voltage from both sides of R9 down to ground?

Maybe your R1-R10 has to high values for your needs.

load resistors installed
I do measure 2,4-2,5 ohm at R1-10. In installed condition.

AC1+2 are 8,5V AC
AC1 - AC2-gnd and vis versa is also 8,5V AC

8,28V R9 7,28V DC

The series resistors are a bit too high when you have 8,5 VAC in. Try to reduce R1-R8 to 1 ohm. If that doesn't help reduce R9 and R10 also.

Bought 1ohms Burt measured 1,2ohms...
Installed one side R4-10, measured 4,2v@x3
Second side just r5+7, measured 3,6v@x3
Load resistors installed

What are the voltages on both sides of R9 and R10? Do you have 1 ohm on all positions?

8,22. R10 (2,2ohm) 7,39
8,4 R9 (1,2) 7,93
Except r10 all the rest is 1,2ohm

Try to short all resistors. You must have 10 volts in as a minimum.

Don not get it wrong. The 10V findings are now a few weeks too late. I was afraid of that during the last few days.... Before I ordered this individuall made transformer, I asked you about it. You said 9V are OK. Well, it's 8.5V now...
The resistances, as they are given, certainly have a meaning? Is shorting all resistors to get a result? Or are the parts on the place not this important?

The resistors are for reducing harmonics. Normally you don't have any but this is a super regulator with ultra smooth raw voltage.
