here we go....Sansui 5500 | Owners Manual, Service Manual, Schematics, Free Download | HiFi Engine
spec says 45watts per channel so that puts it in the same league as the au-5500....
looking at the schematics, looks like you have
30-0-30 winding, orange leads
0-61 volts, purple leads
0-6 volts, blue leads
you can measure dc resistance of these coils to see what kind of current they are capable of...
