Subject: Voltage conversion of the MTM transformer... ?

From: "xylofoam" <lars.frisk@...>

Hi all,

I'm trying to convert the original transformer in my MTM unit from 110V to 240V... According to the service manual the transformer supports all voltages on the primary core (all colours match the schematics (black:0V, brown:100V, white:110V, pink:220V and orange:240V)), but when I reconfigure the tranfsformer to EU (240V) I get absolutely NOTHING on either of the secondaries?!
What am I doing wrong? According to the schematics there is only ONE primay core, but are there really TWO that needs to be in serial, or ?

cheers
