Hi everyone, i am a newbie here and i hope i will find the help i need. I have the above mentioned receiver with standby transformer's primary coil damaged. I have searched the net without success to find any tech data about this transformer. I have only the Sony part number1-437-313-11 and TAM Malaysia M0126. I guess i could find replacement for it, but i need to know the secondary coil voltages and VA. It is 220v on the primary. It has 5 pins on the secondary, the outer two are not used and i have 6.5 ohms between pins 2and 4, 3,9 ohms between 2 and 3, and 3,6 ohms between 3 and 4. Can someone determine looking the schematics what voltage i need on the secondary? This transformer is mounted on a small board called AC board and the only voltage going out of it is 8v to the main cpu. Other 4 pins on the connector CN51 are ground and 3 incoming voltages, i think. There are two transistors right after the transformer and i am wondering if it is 15-0-15 or maybe something else. Any thoughts about it will be highly appreciated.
