I have a customer who wants some very big mods done to his Sansui. Does anyone have any suggestions as who can do them? Thanks
Larry

Here's imho, some thoughts about you could do to not only in that unit but also in almost any audio amp:

Replace all supply electrolytic with Panasonic FC or Grey Elna.
Replace all Electrolytic in the audio path with Elna Cerafine.
Replace all NP Electrolytic with Black Gate type N.
Install IEC320 AC connector and shielded AC cable.
Install some ferrite rings in audio path wires.
Replace feet with good EAR one (as use with Bel Canto gears).

Also you could replace the supply rectifier diodes with fast discrete recovery diodes.

Have fun.

Here's some hot links to some audio parts & acessories:
