Really rare, NOS (never used) genuine Sansui transformer part number 4002294, probably for AU11000. From Sansui service manual for AU11000, main power transformer has part number 4002290, so… I think that is an improved version of power transformer for AU11000, really very rare item!
I have tested it, (transformer was adjusted for 240 V AC, input voltage was 225 V AC), and the voltage results are on picture no.06
I have measured resistance of primary winding, and the results are on the last picture. (please "click" on image to get bigger picture).
Please keep on mind that transformer is really very heavy, so shipping price could not be cheaper, and I will ship to EU countries only!
Sorry, no return and no refund….
Please look carefully at high resolution pictures, because they are part of description. Installation should be done by qualified technician!!
