Sansui AU-999 secondary transformer resistances

Dear experts,
I need help knowing the resistances of the secondaries of a 999 transformer. After having obtained :banana:a multivoltage (heavy) :) transformer for my AU-999 100 VAC version to replace the (missing) original one, I would like to compare the secondaries with a good working unit, if available from someone, just to be safe before installing/switching it on. The wires are 2 x purple, 2 x blue and 1 x green – the others are white, gray and black - I believe, and please correct me if wrong, secondaries will be the same for any transformer primaries, i.e. 100 VAC or 127 VAC.

Thanks in advance!

Do you have a schematic for this unit, the schematic shows 30 volt for the purple, 30 volt for the blue and 4 volt for the green, white is 3 amp, gray is 0.2 amp, and black is 0.35 amp, hope this helps.

Yep! I know those secondary voltages. I would like to know the resistances just to check its before switching it on. In the meantime I took a chance and it worked fine. Thanks anyway!:)
