MP-3, unbalanced output?

OTL Asylum

OTL, Output Transformerless Amplifier User Group.

I have tried to take a unbalanced output from a MP-3 between pin 1 and 2 (also between 1 and 3) but I have lot of 100 Hz hum.
For a measurement please check the added link.
With balanced output I have no problem at all.
To little capacitance in the power supply for B+?
