[CLOSED] DJM 500 Transformer voltage outputs?

Hi Guys,

Got a DJM 500 that wont power up. Have so far tested up to the transformer input and all is fine. Just wondering what I should see on it's output (the 5-core ribbon cable)

Pins are labelled:     S1+    GND    S1-    S2+    S2-

Looking at the schematic in the service manual these outputs appear to go into ac-dc rectifiers so pretty sure the transformer outputs are still AC, just wondering what voltage they should be

Cheers.
