re: KRF-V4550D

found a design fault on the unit.
the top i/o digital input pcb has 2 yellow wires, ac, going directly to a cap which supplies the power to the 3.3v smd regulator.
the main cap on the circuit was very hot and the 470uf smd metal can cap on the reg was also warm.
cut the one yellow ac supply rail to this input and inserted a 1n5408.
Smd reg and caps now cold as they should be.
spent 2 days restoring the unit and dont know if some idiot had replaced the diode with a resistor on the pcb but all sorted.
Magic unit and sounds excellent.
