Encountered the following problem: when increasing the Bottom knob volume there is also an increase in hum. Problem could be that the transformers are to close to the mainboard. Someone here who cured that problem?

Howdy Chris,
More then likely the problem is with the filter capacitors in the low voltage +-15V power supply. This is a common problem with the Bellari equipment. We have also had problems with the voltage regulator transistor in the high voltage power supply creating hum and noise.
Good Luck!
