Replacing of the red AEG rectifier by single diodes is an easy task - most effort is the elimination of all contact resistances on the pots and switches so as the melting of numerous solder joints.

I am surprised by the good sound character and the reliability despite the age (no hot spots on PCB like to observe on various very expensive Mark Levinson amplifier devices) - thus highly recommended for used purchases.
