Modifications:

The capacitors of the power supply should be replaced, as the PS gets hot.
Do set this pre-amp to 240V ~ setting in EU with the mains voltage selector if available, due to the detrimental voltage rise from 220V to 240V~:
the secondary voltage will drop from a 48 Volts to a desired approx. 45 Volts and that causes less heat in the PS.
