Remember that when you want to put the 2 secondaries together to form at center tap, that tey must be put in series. Check that it is right by measuring the two ends, the voltage shall be twice the value of one secondaries.

Thanks oz7aff,
I did measure 24V from two ends, from center tap to one secondary 11.88V, from center tap to the other secondary 12.04V. I thought that was acceptable.

Kind regards
Marko

Then he should replace the two 12V regulators with 10V models.

Ps: in my opinion it should be running on +/- 24V

It is just my opinion that small amp's like this one sound better on at higher voltage.

For Audio one normaly use a Logarithmic potentiometer.

If you only have a linear type, then take a look here:
